The good news about this photo: Her outfit is a jumper and not a dress so the entire party couldn't see her "business". 

I know what you're thinking- thank heavens she's wearing a jumper!  That was my first thought too. 

This was taken Wednesday night at a party and yes that's Lenny Kravitz sitting next to Demi seeming less than impressed.  Reportedly, no one saw her drinking but she was sucking down energy drinks like it was her job.
