Parties! The style, stars and scoop from Hollywood's hottest events

Surprise guest Jared Leto and his brother Shannon spent the evening hanging out with their mom, Constance, at her Linda and Constance jewelry line's display case. "I'm here for dear old mom," Leto said. The actor/rocker then proceeded to give a heartfelt sales pitch about his momma's collection of bangles. "The [rings and the bracelets are] my favorite stuff. But that's the stuff that has already sold, so I guess it's everybody else's favorite too. My mom is very talented," Leto gushed.
