The Hard Rock Hotel & Casino Las Vegas' Vanity nightclub was action-packed on Saturday night (Photo credit: Cody Boor). 

The Hills' Audrina Patridge arrived with Ashlee Simpson's ex, musician Ryan Cabrera, and a few friends close to 1 am. Audrina and Ryan asked that nobody take their picture together, as they were acting very coupley.

While their friends were dancing, Audrina and Ryan sat low and talked all night to each other, remaining hidden from sight. As the night progressed, they were less concerned about remaining hidden and stood up to join their friends, who were dancing with colored light rings. Audrina and Ryan left the club about an hour later, holding hands and were escorted into a Hard Rock Hotel SUV.

Criss Angel arrived alone but immediately met up with Carrot Top for awhile, until Carrot Top went back to his date with an unidenitified blonde. Carrot Top's attention was on his date the whole time and left the club early with her. Criss was mingling with a lot of people at Carrot Top's table, and kept changing positions throughout the night. He seemed to favor a blonde in the group and was able to steal a kiss from her, which turned into a mini make-out session. When the group decided to leave, Criss walked ahead with his body guard and the blonde girl. After they left Vanity, they were escorted into the HRH High Limit Room and into a room in the back.
