Kylie Jenner (@kylizzlemynizzl): Kylie Jenner is the undisputed queen of Snapchat and her snaps give us a first-hand look (even more "personal" than "KUWTK") into her Lip-Kit-filled world. She's a must-add.

(Photo by Steve Granitz/WireImage)

DJ Khaled (@djkhaled305): DJ Khaled became universally beloved at the end of 2015 for his motivational Snapchat account in which he talks to his lion statue, lays in his hammock, waters his plants, urges his followers to "bless up," provides shameless plugs for his apparel line, and insists that "they" don't want you to have literally anything. 

(Photo by gotpap/Bauer-Griffin/GC Images)

Justin Bieber (@rickthesizzler): The Biebs' Snapchat game is on point -- albeit sometimes kind of emo -- though sometimes his inspirational messages leave us scratching our heads and asking, "What do you mean?" 

(Photo by Axelle/Bauer-Griffin/FilmMagic)

Bethenny Frankel (@bethennyfrankel): The "Real Housewife of New York" is a huge fan of Snapchat, and she is one of our new favorite celebrity Snapchatters. Her assistants, her doorman, her driver and her dog all take centerstage and provide some truly hilarious moments.

(Photo by Gilbert Carrasquillo/FilmMagic)

Rihanna (@rihanna): RiRi is a little bit inconsistent with her Snapchat usage, but when she's active, there's nothing funnier. Usually it's her friend/assistant manning the phone, but we get a hilarious look into Rihanna getting ready, getting krunk and messing around with her friends.

(Photo by Axelle/Bauer-Griffin/FilmMagic)

Kim Kardashian (@kimkardashian): Kim Kardashian just joined Snapchat in March of 2016, and, if her first few snaps are any indication, she's going to make great use of the drawing feature.

(Photo by James Devaney/GC Images)

Ashley Benson (@benzo33): We're pretty sure that Ashley Benson, who plays Hannah on "Pretty Little Liars," is recording her life on Snapchat 24/7 ... not that we're complaining, though -- we love watching her mess around with the "PLL" crew.

(Photo by Gregg DeGuire/WireImage)

Gigi Hadid (@itsgigihadid): Gigi Hadid's life is just as glamorous as she is, as proven by her effortlessly chic Snapchat account. The model is a huge fan of mirror selfies and documenting her world travels.

(Photo by Rabbani and Solimene Photography/WireImage)

Joe Jonas (@joseadam): The middle JoBro and frontman of DNCE is known to be quite the jokester, and that reputation continues on his hilariously weird Snapchat. It doesn't hurt that his bandmates are also just as funny.

(Photo by Steve Jennings/Getty Images for iHeartMedia)

Kendall Jenner (@kendalljenner): Kendall isn't as active on Snapchat as her little sister, Kylie, is, but she holds her own with fierce selfies, behind-the-scenes shots on set and shenanigans with her famous family.  

(Photo by Steve Granitz/WireImage)

Reese Witherspoon (@snapsbyreese): The Oscar-winner only Snapchats a couple times a week, but it's quality over quantity, right?! In Reese's case, that's so right. A must-add! 

(Photo by Dimitrios Kambouris/Getty Images for EIF)

Ariana Grande (@moonlightbae): Ariana is another one of those stars on Snapchat who seems to post pretty much everything she does. She makes sure to document her recording process, car rides, hangouts with her brother Frankie and everything else in between. 

(Photo by C Flanigan/Getty Images)

Rob Kardashian (@robphuckedme): The infamously reclusive Kardashian reappeared in early 2016 on Snapchat and, though he doesn't post that often, it gives you a fascinating look into his life as he works on getting back into shape and hangs out with new girlfriend Blac Chyna.

(Photo by Steven Lawton/WireImage)

Lady Gaga (@ladygaga): Lady Gaga joined Snapchat in the lead-up to her amazing Super Bowl "National Anthem" and has been active ever since. We especially love seeing how she puts together her most outrageous looks.

(Photo by Steve Granitz/WireImage)

Khloe Kardashian (@khloekardashian): Khloe Kardashian was the last of the Kardashian-Jenner clan to give into the pressure of getting a Snapchat, and boy are we glad she hopped on board! She frequently makes use of Snapchat lenses and posts funny videos of Lamar, Kylie and Kourtney.

(Photo by J. Countess/Getty Images)

Shay Mitchell (@officialshaym): Just like her "Pretty Little Liars" costar, Ashley Benson, Shay is notorious for documenting the hilarious behind the scenes moments on the hit ABC Family show. Got a secret, can she keep it? No, she'll probably post about it on Snapchat.

(Photo by Allen Berezovsky/Getty Images)

Kate Hudson (@khudsnaps): The actress' amazing Snapchat account follows her fabulous life and celebrity BFFs (and mom Goldie Hawn) from event to event, and we love every second of it.

(Photo by Gregg DeGuire/WireImage)

Meghan Trainor (@mtrainor22): The "All About That Bass" hitmaker is all about fooling around and making fun of her friends on Snapchat, and it makes us love her even more. Consider us as having jumped aboard the M-Train.

(Photo by Allen Berezovsky/Getty Images)

Chris Pratt (@chrisprattsnap): "Jurassic World" star Chris Pratt is just as hilarious on Snapchat as he is on screen, documenting his hard work in the gym and on set.

(Photo by Gabe Ginsberg/WireImage)

Diplo (@diplo3000): Another one of those stars that is literally always active on the social media platform, Diplo is a fan of posting pretty much anything. The DJ is especially fond of taking selfies ... but, let's be real, who isn't?!

(Photo by Jeffrey Mayer/WireImage)

Ryan Seacrest (@ryanseacrest): The TV personality and media mogul isn't that consistently active on Snapchat, but when he's at a big event -- like an iHeartRadio concert or hosting gig -- he documents the backstage happenings as well as anyone.

(Photo by Steve Granitz/WireImage)

Blac Chyna (@blacchynla): Rob Kardashian's new girlfriend and Kylie Jenner's life ruiner Blac Chyna is the queen of trolling the Kardashians on Snapchat, posting tease-worthy photos of Rob Kardashian, Amber Rose, etc.

(Photo by Matt Winkelmeyer/Getty Images)

Fifth Harmony (@fifthharmony): We love the 5H girls, but we really wish they would post on their band's Snapchat account more often. Some of the girls have individual accounts that they're active on, though, which prove that they're still "Worth It."

(Photo by C Flanigan/Getty Images)

Serena Williams (@serenaunmatched): The tennis legend joined Snapchat at the end of last year and posts hilarious selfie confessionals while lying in bed with her pups. And, yes, her sister Venus does make an occasional cameo.

(Photo by Lester Cohen/WireImage)

(Photo by Kevin Winter/Getty Images)

Hailey Baldwin (@haileybisboring): The up and coming model, who's been linked to Justin BIeber, is anything but "boring" on Snapchat. She's totally worth the add.

(Photo by Gabriel Olsen/FilmMagic)

Calvin Harris (@calvinharris): The celebrity DJ and boo thang of Taylor Swift pushes the envelope on Snapchat with his ruthless pranking of friends and shameless shirtless selfies.

(Photo by Adam Bettcher/Getty Images for iHeartMedia)

Paris Hilton (@realparishilton): The socialite turned reality star turned celebrity DJ is always on the move -- it's hard to keep up with her globetrotting ways (seriously, she's literally always in Dubai), but it's worth trying. We particularly like it when she has someone else film her while she proclaims she's "killing it."

(Photo by Gilbert Carrasquillo/FilmMagic)

Eva Longoria (@realevalongoria): The "Telenovela" star is refreshingly candid on Snapchat, which makes us love her even more ... but also makes us wonder what it would've been like for her "Desperate Housewives" character, Gabrielle Solis, to have had an account.

(Photo by Adela Loconte/WireImage)

Chelsea Handler (@chelseahandler): The unfiltered comedian continues her #FreeTheNipple-heavy social media presence on Snapchat, providing hilarious commentary on her everyday life. Our favorite part of her Snapchat? When she talks to her adorable dogs!

(Photo by Kevin Mazur/VF16/WireImage)

Selena Gomez (@selenagomez): The "Good For You" singer is super adorable in her selfie videos on Snapchat, usually taken behind the scenes of a photoshoot or one of her lively concerts. Unfortunately, there haven't been many Bieber sightings though.

(Photo by Andrew Toth/FilmMagic)

Nick Jonas (@jicknonas): The youngest of the Jonas Brothers clearly has fun with his Snapchat account. If you decide to add him, you'll definitely become "Jealous" of his lifestyle. 

(Photo by Mike Marsland/WireImage)

Bella Thorne (@bellathornedab): The rising star doesn't hold anything back on her Snapchat account, hilariously documenting her post-gym fast-food runs and selfies with boyfriend Gregg Sulkin.

(Photo by: Theo Wargo/NBCUniversal/NBCU Photo Bank via Getty Images)

(Photo by Bryan Steffy/Getty Images for Drai's Beachclub-Nightclub)

Keke Palmer (@keekthesneak): The "Scream Queens" star is a Snapchat fanatic, heavily documenting her daily workouts and yoga sessions, hilarious car rides and ample red carpet events. Keke Snapchats a lot, but she's hilarious so we love it.

(Photo by Allen Berezovsky/WireImage)

Brody Jenner (@nextjenneration): There's another member of the Kardashian/Jenner clan on Snapchat, and it's former star of "The Hills," Brody. When he announced he joined the social media platform he said it was "time to get weird on Snapchat," but he doesn't post that often on his account, so ...

(Photo by Mindy Small/FilmMagic)

Ansel Elgort (@anselelgort): The "Fault In Our Stars" actor, DJ and perpetual goofball isn't afraid to get silly on Snapchat while traveling the world and hanging out in Brooklyn with his girlfriend.

(Photo by Jason LaVeris/FilmMagic)

Tyga (@lamboluxury): Rapper and boyfriend of Kylie Jenner may not be able to keep up with his girlfriend's Snapchat game, but he still holds his own. The couple isn't afraid to show affection on Snapchat, either, even if it makes headlines.

(Photo by Jason LaVeris/FilmMagic)

(Photo by Mark Davis/DCNYRE2016/Getty Images for dcp)
