Selena Gomez, Demi Lovato and Alicia Keys glammed up for Variety's unite4:good's first-ever 'unite4:humanity' event in Los Angeles on Thursday (Feb. 27). The lovely and stylish ladies were on site to pick up awards, too!

Gomez sparkled in a winter white Berardi jumpsuit with a bejeweled bodice and even thanked Lovato during her acceptance speech for her Young Visionary Award, saying that her fellow singer inspires her and that she hopes they can inspire others.

Lovato, known for her rock chick chic, wore a short, black leather dress with scalloped straps and intricate patterns. It showed off her curves. She actually performed, while her rumored BF Wilmer Valderama was in the crowd supporting her. Lovato pocketed the Young Luminary Award.

Keys, wearing a long black dress with a corseted bodice, nabbed the Music Visionary Awards.

The ruby red lips were a bold contrast.

Sel also posed with her award, posting: "By far the coolest award I've received -Young humanitarian award! Beyond proud to represent UNICEF since I was 17."

Lovato's LLBD -- that's leather little black dress -- was supremely sexy.

Her rock chic aesthetic served her well.

Alicia Keys usually favors black on red carpets, and this simple gown looked amazing on her, even with the strangely chunky shoes.
