Katy Perry is set to face the wrath of Paris Hilton - she's reportedly dating the socialite's ex Benji Madden.
The I Kissed A Girl hitmaker was spotted getting close to the Good Charlotte rocker at Las Vegas nightclub Lavo on Saturday night (14Feb09), according to People.com.
Perry recently split from Gym Class Heroes star Travis MCCoy. Hilton and Good Charlotte rocker Madden broke up in November (08) after nine months together.
