Selena Gomez Goes Blonde for the American Music Awards — Plus More Red Carpet Looks!

The American Music Awards are here — and the stars did not disappoint on the red carpet. Selena Gomez turned heads when she debuted a new blonde bob, which we have a feeling Justin Bieber loves while Demi Lovato, Pink, and a pregnant and glowing Jessie James Decker looked flawless.

Hosted by Tracee Ellis Ross, the 2017 show is bigger than ever with performances from Demi, who brought transgender lawmaker Danica Roem as her date, Christina Aguilera, Lady Gaga, and Kelly Clarkson. "It’s [Kelly's] 15th anniversary of winning American Idol, so she’s gonna throw it back to her very first hit, as well as doing her newest single," AMA producer Mark Bracco told ABC News. "And then Pink … is doing something that has never been done before … and it’s insane in the best possible way."

Christina will also be singing a medley of Whitney Houston songs from The Bodyguard soundtrack, which is celebrating its 25th anniversary, while Diana Ross will be receiving the Lifetime Achievement Award. "There’s so much of an emphasis on youth, but to see a woman whose career has spanned so many decades, that is still performing, still on stage, still singing live, still looking gorgeous… it shows you what’s possible," her daughter Tracee said. "And people who’ve never seen her… it’s worth it!"
