Katy Perry has drawn blood in remembrance of the biggest performance of her career.

The 30-year-old, who wowed this week’s Super Bowl audience with a dizzying halftime show, has hit the tattoo parlour to get roman numerals representing this year’s competition, etched into a finger.

“I thought it would be appropriate to draw blood tonight… XLIX” she said on Instagram.

🔥XLIX🔥
