Not only did Jenny Lewis direct and star in her new music video for "Just One of the Guys," but she recruited some famous friends and got them to dress in drag for the vid -- loves it!

Kristen Stewart, Anne Hathaway and Brie Larson appear as both ladies and as douchey-looking guys, and while Lewis also dons dude attire, she rocks a rainbow suit and guitar while her gal pals are in white ensembles.

"We screamed with laughter all day, huddled behind the monitor," Lewis tells GQ.com. "I haven't laughed that hard since What About Bob? came out on laser disk." So how did the ladies figure out their respective looks? "The rat tail was all Annie," Lewis said. "Deep character exploration. Her dude is a bit more Backstreet Boy than the rest. Melancholy Backstreet Boy is what I think she was going for—he really feels things deeply and break dances like a motherf*cker."

How about Lewis? "My dude is clearly the gnarliest. He's a total d*ck—like a mini Bonaduce/Durst hybrid." Sounds about right!
