Kim Kardashian may be a knockout -- but she almost got KO'd herself in a celebrity beat-down.
The entire Kardashian clan took place in the match, held to raise money for the Dream Foundation. Aspiring boxers bid cash to take a spin in the ring with the reality diva and her clan -- and Kim K. took a serious blow to the face.
"Man, my girl could throw a punch! Look at my black eye!" Kim wrote in her blog.
"I didn't want to let the charity down, so I decided to get in the ring," said Kim, who wore a girly all-pink boxing outfit, complete with bright pink boxing gloves, to take a turn as Muhammad Ali.
Stepdad and former Olympian Bruce Jenner as well as Kardashian's brother Rob also took their turn in the ring, and both got their fair share of an old-school beat-down.
"At one point Rob's mask fell off and when he put his hands down, he got hit in the face and ended up in the hospital with a concussion," Kim wrote. "Rob's a strong guy and can definitely hold his own, but he wasn't expecting to get hit after his mask had fallen off."
"This guy just got really down and dirty," she said.
The Kardashians raised over $11,000 for the charity.
