John and Minka do Butter

He loves me, he loves me not! We caught up with singer John Mayer on what seems like his regular Monday night outing to NYC club Butter earlier today. And it certainly wasn't actress Cameron Diaz who was on his arm. Rumors are John and Cam hooked up in New York last weekend, but last night new girlfriend Minka Kelly was in tow to make sure her man got up to no funny business.
