Spears took to Instagram on Monday to show off the bruises on her legs that she's gotten while preparing for her big return to stage, and we're in pain just looking at them.

In the caption to accompany the bruise-filled photo, Spears wrote, "Someone jokingly asked me what the hell I did yesterday... check out my bruises that's what I did! Working hard on the new show! Get ready!!"

Though we weren't aware of her injuries, we did know that Brit Brit was putting in the work already. She had previously posted teasers of some new choreography that we can expect to see at her insanely popular Vegas residency upon its return on Feb. 13.
