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.
Partynextdoor arrives at the 2017 Billboard Music Awards.

Lea Michele flashed her undies in a sheer ensemble, while Rita Ora gave cameras an eyeful with her super see-through bottom.

Noah Cyrus looked oh-so-chic in a matching crop top and trousers combo that showed off her flat tummy. The singer brought her whole family as her dates, and they looked way too cute together!

Jesse James Decker also had jaws dropping as she showed off her curvaceous body in a jumpsuit with some pretty revealing cutouts.

Check out all the hottest looks of the night in the slideshow above.

Billboard Music Awards 2017: Worst dressed
Should have left this outfit in the backseat of her Rover. Halsey paired a bra -- an ill-fitting one, at that -- with a floor length khaki skirt. (Do those even exist?) If that wasn't enough, she then tacked on these ridiculous lace-up gray sandals.
Kendall Jenner pulled it off at the Met Gala, but Rita Ora's attempt at the major thong look just looks kind of trashy. (Sorry!) It could have been a great look if she paired tailored black pants or a black leather mini with her cute top!
Sorry, Z LaLa -- you're no Lady Gaga. This bizarre getup is bad enough from neck down, but just think how awful the evening is going to be for everyone sitting behind her.
Sorry, what? Dencia's architectural wonder may have taken hours upon hours to produce, but it should have just stayed on the drawing board.
Not quite sure what to make of Jane Zhang's outfit? We aren't either. Everything's mismatched, from the chess-board belt to the ridiculous giant pockets, right down to the gray stilettos. Whoops.
Tyler Hubbard (L) and Brian Kelley of Florida Georgia Line have written tons of hits, but they don't seem to have the same knack for fashion. We're not sure which outfit is worse -- but we might have to hand it to Brian, because that silk scarf is just weird.
Maia Mitchell's outfit isn't awful on its own, but it just doesn't quite fit her body: The actress looks like she's drowning in the cropped jacket and flared skirt.
Hailee Steinfeld has walked countless red carpets, and while we love seeing her try something new, this looks just falls flat. From head to toe, it's just a mess.
Let's just be blunt: Logan Paul looks like he just got off his shift at Hot Topic. The graphic hoodie just doesn't fit the occasion -- or any occasion, really.
Jason DeRulo's velour jacket looks more like something Alec Baldwin would wear in an ill-fated "Saturday Night Live" sketch. Dude, it's hot out -- leave the velvet behind!
She's a Barbie Girl...! Keltie Knight's bubblegum-pink dress was cute, but her shoes completely clashed -- and it kind of looks like she just forgot to do her hair.

Yikes! We're not sure what to make of Sibley Scoles' Egyptian-intergalactic-inspired number -- because we're afraid she'll send her overlord after us.
