The Billboard Music Awards took over Las Vegas on Sunday, and the music world's biggest stars came out for the occasion. The night was jam-packed with adorable PDA, jaw-dropping fashion, and of course, a flood of electric performances. Keep reading to see the night's biggest highlights, including Britney Spears's first time performing "Pretty Girls" live [1] and an adorable acceptance speech from Sam Smith.
- Let's go back to where it all started: the red carpet. Take a gander at all the stars who were in attendance [2] and all the gorgeous outfits they wore [3].
- Don't forget to zoom in on all the gorgeous hair and makeup [4] from the evening.
- We couldn't help but notice a bit of an alternative edge among some of the night's guests! Check how these two stars showed off their tattoos with cutout dresses [5].
- By the way, did you catch that sneak preview of the Balmain and H&M collaboration [6]? We can't wait until it hits stores.
- When it comes to the red carpet, there were certainly a handful of standouts. We still haven't recovered from the amount of skin Jennifer Lopez's outfit [7] showcased, and Chrissy Teigen's sheer dress [8] blew us away.
- Meanwhile, Taylor Swift [9]'s squad game was seriously strong: she walked the red carpet [10] with a whole slew of friends by her side.
- Kendall Jenner was looking fierce, sure, but did you also catch her sweet words about Bruce Jenner [11]?
- The energy kicked up even higher once the show started. One Direction won the first award of the night, and they even gave a shout-out to Zayn Malik [12] in their acceptance speech.
- Can we talk about all the couples from the night [13], though? Taylor Swift [14] and Calvin Harris shared a supersweet moment [15] before she took the stage, and Britney Spears [16] made her first red carpet appearance with new beau Charlie Ebersol [17].
- Oh, and what's the deal with Jennifer Lopez [18] and Casper Smart? They looked pretty cozy together in the audience [19].
- On the stage, numerous performances throttled the audience in the best way. Nick Jonas [20] performed his hit song "Jealous," [21] and we have to say, he looked (and sounded) better than ever.
- Meghan Trainor and John Legend [22], on the other hand, slowed things down with a soulful rendition of "Like I'm Gonna Lose You." [23] And Wiz Khalifa made us cry yet again with his Furious 7 song, "See You Again." [24]
- Remember Faith Hill [25]? You surely will after you watch her singing "Girl Crush" [26] with the band Little Big Town.
- We've saved the best for last! Mariah Carey [27] blew us away with her minimedley [28], which included an epic throwback to her early days.
- The cutest acceptance speech of the night had to be Sam Smith's. He totally re-created that iconic Love Actually scene [29], and we loved every second of it.
- The most anticipated performance of the night was probably Britney Spears and Iggy Azalea's "Pretty Girls." [30] Predictably, the two divas totally killed it.
