Wade's Blushing!

If you wanna really party, party in Vegas!

Check out Britney Spears' former choreographer Wade Robson (the one responsible for her split with Justin) celebrating his 26th birthday at the Wynn Las Vegas' Blush nightclub this past Saturday... with Brit's other "ex" Criss Angel! Was it awkward? Not from the looks of these pix!

Also in attendance was Wade's wife Amanda and a certain Girl Next Door:

Wow, so Holly Madison and Criss Angel hanging out in Vegas AGAIN. Are they really just friends, or is something more going on here?

Seems there's definitely more going on - sources say Criss and Holly were "dancing and kissing" during the night. Uh-oh, what would the Hef think!
