Looks like Katy Perry may be trading in a pair of lady lips for those of Paris Hilton's ex!
According to People.com, Katy was canoodling big time with Good Charlotte's Benji Madden on Valentine's Day. After Katy performed at the Hard Rock Hotel's Wasted Space, she and Benji head to Lavo, where an onlooker sensed "some chemistry there."
Nice! Totally a cute couple -- dontcha think?
