Pete Wentz Strips to His Boxer Briefs

Here are some exclusive shots of Fall Out Boy frontman Pete Wentz in his boxer briefs (and sexy tube socks) and the rest of the boys from the Honda Civic Tour in their underwear during their last concert together earlier this month in Anaheim, Calif.

Ashlee Simpson cheered on her underwear-clad boyfriend Pete and the boys from backstage. Ra-ra-ra!

Also pictured: The Butcher from The Academy Is, Andy Hurley from Fall Out Boy, and evening’s M.C., known as Dirty.
