Nicole Richie‘s reps are denying claims that she was involved in any sort of altercation this weekend in Las Vegas.

It was first reported that Nicole Richie got into a verbal altercation with a woman outside of the Hardrock Hotel in Vegas this weekend where she attended a party at new nightclub Wasted Space, which fiance Joel Madden has a hand in.

The two women apparently got into it over a taxi, with Nicole having to be escorted off the premises.

Nicole’s camp is now denying that anything happened, saying Nicole was at the Hardrock that night,  but there wasn’t an altercation of any kind involving her.
