Is Katy Perry SURE She’s Not Dating Benji Madden?

Katy Perry, 24, has personally denied that she is involved with Paris Hilton’s ex, Good Charlotte member Benji Madden.

But judging from these pics, taken Saturday, they seem to be awfully close.

Perry and Madden were photographed together in Las Vegas on Valentine’s Day at the Lavo lounge at the Palazzo hotel, where Perry was deejaying.

The two were allegedly unable to keep their hands off each other earlier in the evening at the Hard Rock Casino’s Wasted Space club after a Perry performance, according to The Daily Mail.

Despite Perry’s protestations that the hook-up rumors were “just how the media works,” the two were spotted at Lavo yet again on Saturday night. And, as you can see, Perry was practically sitting in the Good Charlotte guitarist’s lap.

Both Perry and Madden have experienced breakups in recent months. Perry split with Gym Class Heroes frontman Travis McCoy in January, and Madden split with celebrity heiress Paris Hilton last November.
