Holly Madison and Criss Angel continue to spend more and more time together.
Though they are still denying their relationship, there was no hiding it in Las Vegas this past weekend!
The pair are dating - or at least hooking up regularly - and they're not going to great lengths to keep it private.
On Saturday, Hugh Hefner's #1 girlfriend and the illusionist were pAArtying it up at Blush nightclub in Sin City's Wynn Hotel (above).
And, sources reveal exclusively to PerezHilton.com that "Holly and Criss were seen dancing and kissing" throughout the night.
What will Hugh think about that????
