What's a girl to do after she completely nails her 2015 Super Bowl Halftime performance? Get a tattoo to commemorate the iconic event, obvs.

After Katy Perry dazzled the entire stadium with her unbelievable stage presence (and those sparkling fiery antics), the 'Roar' singer took to Instagram to document the process of her Super Bowl inking.

"I thought it would be appropriate to draw blood tonight… XLIX," Katy captioned the shot of herself going under the needle, grimacing slightly as the tattoo artist works on her hand. She then shared the finished product: The roman numerals 'XLIX' delicately inked in black on the inside of her ring finger. (Side note: We're seriously impressed with the tattoo artist's steady hands. That is some serious precision right there!)

Katy Cats, check out Katy's Super Bowl tat in the photo below. What do you think of her permanent commemoration of the event?
