Nicole Richie was in Las Vegas this weekend and she managed to get herself into a little trouble while there.

Nicole was partying at Wasted Space inside the Hard Rock Saturday night with Carey Hart and of course the Madden boys when she got into an argument with another female who was also at the club. It happened at approximately 1:00 AM.

Sources say Nicole was so fired up that security had to be called to remove her from the premises.

The Hard Rock Hotel & Casino has refused to comment and Nicole’s publicist is denying she was involved in the altercation. “She was in Vegas but there wasn’t an altercation of any kind involving her.”
