The hotel heiress helped host the party for her relative, Brooke Wiederhorn, taking the group to watch Britney Spears' Britney: Piece of Me show at the Planet Hollywood Resort and Casino.

The party also went to the Beachers Madhouse venue and to see the Thunder From Down Under, a male stripper show at the Excalibur Hotel, during which Hilton and the bride-to-be were pulled on stage to dance with the semi-naked hunks.

A picture posted online shows Hilton and members of the bachelorette party sitting on the dancers' laps, and the socialite added in a caption on, "Went to my 1st bachelorette party & 1st male strip club in my life this weekend. Thanks @ThunderVegas for an unforgettable night! #BrookesBachelorette (sic)."
