Washington, November 26 : Paris Hilton, who recently split with rocker Benji Madden, was spotted at Crystal Audigier's birthday bash - despite reportedly telling party planners about her possible appearance to support her ex-beau for his band's album release party.
The hotel heiress was seen by the Pop Tarts spies letting her hair down with sister Nicky while the Pussycat Dolls performed at the star-studded bash.
Meanwhile, the guitarist and backup vocalist of the band 'Good Charlotte' too was said to be in high spirits and was seen enjoying the party on the occasion of his band's "Greatest Remixes" album.
"Benji even did some harmless flirting with some cute girls at the bar," Fox News quoted a source as saying.
While Paris has kept her hands full by spending recent evenings out with gal pal Avril Lavgine and hosting the Pussycat Dolls post-American Music Awards bash at the Viper Room, Benji recently took to the turntables in Las Vegas' Hard Rock Hotel and Casino hanging out with pal Carey Hart.
