Dancing With The Stars’ Mark Ballas celebrates his birthday  topless (thank you jesus) at Liquid Pool Lounge inside Aria in City Center Las Vegas yesterday. Mark turned 25 on May 24th.

Karen Koeningsberg celebrated with Mark. I’m not sure who she is…is this his girlfriend? I can’t keep up. I thought he was with Pia Toscano?

Is This DWTS’ Maksim Chmerkovskiy’s LAST Season?

I feel bad for Mark because he and Chelsea Kane TOTALLY deserved to win the mirrored disco trophy this season on Dancing With The Stars. Don’t get me wrong, I love me some Kirstie Alley and I like Hines Ward a lot (and felt Kym Johnson deserved a mirror ball trophy) but of the three Chelsea was by far the best dancer. By far. It reminds me of the time when Mark was paired up with Sabrina Bryan and she got voted off WAY too early.
