Nick Carter celebrated his 29th birthday at the Key Club last night, where band mate AJ McLean, brother Aaron and former rival boy bander JC Chasez showed up to reminisce about the good times back in the late 90s when they were all still relevant. I kid!

We must admit, Nick's looking kind of good these days!

Nick Carter And aww, little bro Aaron's all grown up...too bad he's still got the acne, though. Someone get that guy some Proactiv!

(Check out the gallery to see who's looking a little worse for wear these days...)
