Sophia Bush & Chelsea Handler: Belvedere Party!

Sophia Bush and Chelsea Handler arrive at the (Belvedere) Red Pre-Grammys party on Thursday (February 9) at Avalon in Hollywood.

The 29-year-old actress rocked a Paule Ka black leather cocktail dress. She and Chelsea both accessorized with Edie Parker clutches.

Guests at the bash, which benefited the (Red) initiative to eliminate AIDS, enjoyed a performance by Mary J. Blige.

“Mary J is everything! And she’s using music to raise awareness for @joinRED. Now THAT really is everything,” Sophia tweeted.

FYI: Chelsea is wearing a Thierry Mugler dress, Frye boots, a Des Kohan cuff, and Beckley earrings.
