Jamie-Lynn Sigler (in Nicole Miller), Jenna Dewan (in Valentino) and Lea Michele (in Emilio Pucci) stepped into spring at this weekend's Chrysalis Butterfly Ball in Los Angeles, a benefit for the non-profit organization that helps to provide jobs for the homeless and low-income individuals. "I had such an amazing time last night at the Chrysalis Ball! It was such honor to be there and truly an inspiring night," Michele tweeted. The Glee star accessorized with Pomellato jewels and a Fendi bag. See more stars at last weekend's hottest events in the gallery.
