"Katy Perry finger-banged my cleavage. It was a weird night," Anna said about her Grammys encounter with the singer during an appearance on Conan. "She's very mature!"
Then, when the two were bumped into each other two days after the Grammys at a Stand Up to Cancer event, Katy got grabby again!
In this playful photo, Katy is seen going in for the kill.
"The girl can't help it," Anna wrote when she posted the photo on Twitter.
Of course, that isn't the most scandalous thing the "Roar" singer has done lately. On Super Bowl Sunday, Katy and boyfriend John Mayer went to a strip club in Santa Barbara, where she reportedly made it rain!
And that isn't the first time the celeb couple has been spotted at a strip club.
Hey, the girl likes to have fun!
