Ashlee and Pete hung around Chicago last weekend and hit up the Hard Rock Hotel for the club owner's 40th birthday party. Unfortunately, it doesn't sound like Ashlee had all that much fun. Page Six reports: "Simpson refused to let any girl come between herself and her man. When female fans tried to take their pictures with Wentz, Simpson 'got whiny and dragged him away,' a spy said." These two have been pretty cozy for awhile now, but it sounds like Ashlee is not a fan of Pete's groupies and may even be questioning his loyalty. We might also considering the things that he has said in the past.
