This Sunday on 'Keeping Up with the Kardashians,' Kim takes several blows to the face during a charity boxing match with a female fan.
"I've never been hit so hard," she says in the clip.
"The boxing match was crazy! I'm a little banged up today but all worth it for charity!!!," she tweeted after filming the match in November.
In the episode Kim's stepdad, Bruce Jenner, also takes a turn in the ring.
