Billboard Music Awards 2017: Best of beauty

It's the hottest awards show this summer -- literally.

The 2017 Billboard Music Awards took place in sunny Las Vegas, Nevada, on Sunday afternoon. The award show honored some of the most popular names in the music biz -- DJ Khaled, Hailee Steinfeld and Lea Michele were just some of the night's famous attendees.

Not surprisingly, the magenta carpet was filled with red hot looks to go with Vegas' nearly 100-degree heat. How they stayed both gorgeous and composed in the sweltering desert, we'll never know. Not a stray hair or shiny T-zone in sight, our favorite stars showed us how it's done.

Hailee's chic look was achieved with celebrity hairstylist Gregory Russell. Here's how you can get the look at home.

1. Start by washing and conditioning hair with Matrix Biolage R.A.W. Shampoo and Conditioner.

2. On damp hair, apply Matrix Style Link Volume Builder Mousse from root to end.

3. Spray Matrix Style Link Heat buffer on hair then blow dry away from the face and through the ends using a large round brush.

4. Select a deep part.

5. Taking 1-inch sections at a time, curl hair (all in the same direction) with a 1.5" iron, pinning each curl to cool and set.

6. Once cooled, brushed out the waves and apply Matrix Style Link Over Achiever through the ends to add structure and shine.

7. Apply Matrix Style Link Super Fixer gel through the roots to hold the hair away from the face and used flat hair pins to set.

8. Diffuse the gelled areas for 10 minutes then spray with Matrix Style Link Style Fixer for hold.

Presenter Kate Beckinsale was easily the beauty front-runner of the night. The stunning actress walked in a messy ponytail, as well as light lips and dramatic eyes to perfectly complement her sequined gown. Other favorites included Baywatch's Alexandra Daddario and Oliva Munn -- theyboth looked radiant.

Another memorable moment was the legendary Celine Dion performance of "My Heart Will Go On" in honor of the 20th anniversary of "Titanic". Everyone was talking about her incredible performance and memorable outfit, even though she skipped the red carpet.

Billboard Music Awards 2017: Red carpet arrivals
Vanessa Hudgens was one of the best-dressed of the night in a nude floor-length number with large bows. So gorgeous!
Is it hot in here?! Lea Michele heated things up -- and showed off her svelte physique -- in this ultra-sexy black dress. She (rightfully) let the outfit do all the talking, sweeping her hair up in a neat bun.

Hailee Steinfeld, a consistent red-carpet winner, donned a semi-sheer calf-length number over black undergarments. The slicked-back hair and minimal makeup allowed her ensemble to take center stage.

Olivia Munn's sheer black dress, featuring floral appliques, seems conservative at first glance -- but sans bra and (possibly) full-coverage panties, it's definitely a risky ensemble!

He has arrived! Jason Derulo looked dapper in a fancy tux with some teal detailing.

Leggy lady! "Baywatch" star Alexandra Daddario looked incredibly sexy in a dress with a slit that reached all the way above her hip.

Va-va-voom! Camila Cabello embraced her inner Jessica Rabbit with this floor-length red number. Loving the '90s-esque spaghetti straps!
This is definitely.. something. Halsey opted to go shirtless in a classic demi-cup bra -- and then inexplicably went for thigh-high gladiator sandals and a floor-length khaki skirt.
Hot mama! Jessie James Decker's black cutout jumpsuit left little to the imagination -- but she still managed to look classy. And how prom-perfect is her hair?
Stunning! Nicole Scherzinger sent pulses racing in a super-sexy orange ruffled number -- and there's no denying that her figure is slammin'.
Handsome as ever! John Legend wore a double-breasted navy suit over a collared white shirt -- and broke the "don't mix black and blue" rule with black loafers.
Ashley Tisdale is effortlessly stunning in a strapless black wide-leg jumpsuit.
'Bachelorette' Rachel Lindsay is pretty as a picture in a simple black sheath and black strappy stilettos. Someone get her a rose!
Quite the country duo! Billy Ray Cyrus dressed down in light-wash jeans and shades, while wife Tish Cyrus topped off a bright white pantsuit with an unexpected wide-brimmed hat.
Rebecca Black's navy mini is cute as is, but the fun, unexpected pumps give the whole outfit a boost! She's come a long way since her "Friday" days!
Cool BBMA style? It looks something just like this. The Chainsmokers dressed down in camo and denim, but with skinny tailored pants and coiffed hair, they still looked event-appropriate.
All grown up! Noah Cyrus went for black-on-black -- plus ultra-dark locks -- with a lingerie-style bra top and grungy jeans.
Sam Hunt made hearts melt in a clean black tux and smart bowtie.
Hopefully it's not too hot outside! Jason DeRulo's velvet coat looks heavy, but the mint green lapels are admittedly very May-appropriate.
Baby, you're a firework! Kate Beckinsale looks better than ever in a deep-V number seemingly inspired by the Fourth of July.
Jason Kennedy, a total red-carpet pro, wore a perfectly-tailored maroon suit and fresh white sneakers -- an all-around winning look.
The top may be conservative, but Rita Ora bared her whole front and behind in a fishnet-style skirt (or something) that showed off a black thong.
Doing his dad proud! Prince Michael Jackson looked fashion-forward yet comfortable in a black bomber jacket and cropped white jeans.
Musician Lindsey Stirling, a lauded violinist, wore a mixed-media gown adorned with Grecian-inspired gold leaves.
Singer Shawn Hook put a twist on his all-black ensemble with a mustard bomber jacket.
Singer Bebe Rexha kept things classic but sexy in a cleavage-baring black gown.
Mark Cuban knows how to work corporate casual! The "Shark Tank" investor kept things simple in a crisp collared shirt and navy suit.
Whew! We were so distracted by Z LaLa's planet-sized headpiece that we almost didn't notice she went nearly-nude in a dress made of... plastic?
Dapper! Rapper Machine Gun Kelly ditched the boring black suit for a smart blue patterned ensemble -- and worked the classic pointed finger pose for good measure.
Goth meets springtime! Singer Taylor Grey's unique sweetheart-neckline mini was feminine yet rocker-chic.
Chris Daughtry -- possible future 'American Idol' judge! -- wore a perfectly-fitted navy suit with a skinny tie. We think even Simon Cowell would approve.
The sharks have arrived! At first glance, Daymond John's outfit is nothing exciting -- until you notice the baby blue tie and gingham shirt. Ditch the leather jacket, Daymond, we want to see the whole look!
Quite a look! ibley Scoles bared her cleavage and a whole lot of leg in this unexpected gray number.
No fault in this star! Ansel Elgort stuck to black-on-black, finishing off the look with a sleek leather jacket.
Go big or go home! Brandi Cyrus stood out from the crowd in a cerulean suit dotted with stars, which she left unbuttoned over a metallic bra top.
Does he get style inspo from Robin Thicke? Tyler Hubbard of Florida Georgia Line's black and white suit turned heads on the pink carpet -- and while it's a risky look, he seemed pretty confident!
Dang! Jeannie Mai was pink-carpet perfection in a sultry black maxi that showed off a whole lot of leg. (And may we say, those are some toned thighs!)
Major ballerina vibes from Madison Beer's navy dress, which flared out to the knee with layers of tulle. Her pointed-toe heels made her look like a total prima ballerina!
We're getting dizzy -- in a good way! Rachel Platten went all-in on a bold patterned one-sleeved number, toning down the drama with a messy pony.
Here she is...! Miss America 2017 Savvy Shields wasn't wearing her crown, but this sultry red gown was more than enough to prove her title.
Singer Julia Michaels shows off her enviable torso in a strappy bra top, cropped black pants and a bold silk caftan.
Never one to shy away from the cameras, DJ Khaled hammed it up in a shiny blue bomber and bright white kicks.
Social media star Logan Paul played up the skater boy vibes with windswept hair and a bold hoodie.
Hey there! Amanda Cerny's bustier-style top wasn't a traditional choice, but she upped the glamour with long waves and a strappy stiletto.
Actress Laura Marano isn't afraid of mixing things up! She paired her sequinned tulle ankle-brushing skirt with a sheer black crop top.
Wow! If Dencia was looking for attention, she definitely got it in this architectural design. (Hopefully it unzips in the back, because otherwise, bathroom trips aren't going to be fun.) 
So on-trend! Singer Whitney Woerz added a black choker to her cutout black jumpsuit -- and rocked a red lip.
Ow ow! Josh Duhamel was every woman's fantasy in this perfectly-fitted maroon suit -- and adorably scruffy facial hair.
