Pete Wentz sunglasses divorce sneakers studio fall out boy

Yesterday Pete Wentz was snapped leaving the recording studio in Hollywood, and the tatted up rocker was in a chipper mood yet again!

It was revealed some time ago that Pete has bipolar disorder, and while many people expected him to become more withdrawn following his split from wife Ashlee Simpson, it seems like the divorce announcement has had the opposite effect! Or maybe he's celebrating because he can wear his hair however he wants now? Who knows, but we're loving the new and improved Fall Out Boy bassist!
