Check back, as we'll be live updating with new Billboard Music Awards red carpet pics of our favorite pop stars!

Selena Gomez was white hot in a clingy, halter-style gown by Atelier Versace, complete with neon accents and a peek-a-boo line in the bodice. Hi, sideboob! She wore her hair in a loose, high pony.

Miley Cyrus rocked a court jester-inspired pantsuit by Balmain that mixed black and white checks with crocheted panels. Um, okay...

Jennifer Lopez was a golden goddess in Zuhair Murad, and she also showed off some sideboob.

Taylor Swift was leggy in a sapphire mini by Zuhair Murad that showed off her gams.

Red hot. That was Nicki Minaj tonight. Although her boobies do look a little squished in that bustier top.

Breezy went casual in a print sweater and with some bling.

Kesha showed off a new "category" of wardrobe malfunction. She's got sidecheek! Check out that slit in her Givenchy LBD. That's daring, but she's got the body and the confidence to pull it out.

Ariana Grande is proving to be a style star with her red carpet choices, and she's not even 20. Her flirty black dress with a sweetheart neckline was adorable.

Wiz Khalifa's baby mama Amber Rose, who gave birth to their son in February, was darling in a loose and flowy LBD that showed off her legs.

Ginger kid Ed Sheeran went super casual in jeans and sneakers.

Cali trio and former 'X Factor' hopefuls Emblem3 did the same, with a bit more styling, via ties and jackets.

Icona Pop were anything but basic in black.
