Time to take off that purity ring, Joe!

The Jonas bro had dinner with his ex-girlfriend, actress/singer Chelsea Staub, at super-romantic restaurant Madeo on Saturday night... but then he decided to drop her off back home and go stag to the A-list festivities at Chateau Marmont!

Maybe he thought he could find someone new in that snazzy suit of his? Just make sure it's not Lindsay Lohan - Joe doesn't need that kind of trouble!
