Jerry Ferrara, Jamie-Lynn Sigler, Amaury Nolasco, Adrian Grenier, Kevin Dillon, Kevin Connolly, Chelsea Handler, Amanda Bynes, AnnaLynne McCord, Angie Harmon, Jason Seahorn, Lance Bass, Eve, Mark Wahlberg, and Chace Crawford attended last night's 8th Annual Chrysalis Butterfly Benefit Ball held at a private residence in
Los Angeles.

It was all for a great cause as proceeds went to helping disadvantaged citizens become self-sufficient.

Chrysalis is a nonprofit organization dedicated to helping economically disadvantaged and homeless individuals become self-sufficient through employment opportunities. It currently helps more than 2,000 individuals a year change their lives through jobs.

Looks like this particular charity is special to the Entourage cast, as everyone including Mark showed up to walk the red carpet!
