Forget frogs and locust. Surely a Joe Jonas/Britney Spears hookup would be a sign of an upcoming apocalypse. But before you reach for your rosary, don’t panic–the uber-odd duo didn’t officially get it on…just the next closest thing. Joe was pulled onstage during Brit’s London concert and “treated” to a spicy striptease. Take a good long look at this pic and tell me if you think JB looks turned on…or totally grossed out?
