Katy Perry gets XLIX tattoo.

Katy Perry killed it with a stellar performance during the Super Bowl XLIX half time show on Sunday (Feb. 1), bringing out Lenny Kravitz and Missy Elliot.

During the show, the pop star ran through a medley of hits, including “Roar,” “I Kissed a Girl” and “Dark Horse”, before Elliot assisted with her own hits “Get Ur Freak On,” “Work It” and “Lose Control.”

It was Perry’s first Super Bowl performance, so she celebrated by branding herself with a new tattoo.

“I thought it would be appropriate to draw blood tonight… XLIX,” Perry caption in a photo of her new tattoo of “XLIX” on her finger.
