Trouble in paradise... again?

Nick Lachey attended Maxim's Annual Hot 100 party last night without his current ladylove, Vanessa Minnillo. Hmm, wonder why? Let's hope they didn't split for the second time!

Think ex Jessica Simpson would want to reunite with Nick if her recent kiss with Tony was really just a friendly peck on the cheek?
