Katy Perry [1] sealed her epic Super Bowl halftime show performance [2] in ink on Sunday night; the singer shared a photo on Instagram [3] while getting a tattoo, writing, "I thought it would be appropriate to draw blood tonight... XLIX." She followed up the post with a close-up shot of her finished ink [4], the roman numerals for 49.

After getting her commemorative tattoo, Katy linked up with her fellow performer Missy Elliott at a Super Bowl afterparty — the two ladies hit the stage during the halftime show [5] for a medley of Missy's classic hits like "Lose Control" and "Get Ur Freak On." The rapper shared a photo on Twitter [6] of herself, Katy, and Katy's rumored on-again boyfriend, John Mayer [7], adding more fuel to reports that the two have rekindled their romance [8] after splitting last February.
