Ever want to knock out a Kardashian?

Five lucky bidders are getting the chance to step into the ring with reality TV sisters Kim and Khloe (sans pregnant Kourtney), brother Robert, stepfather Bruce Jenner and Kourtney's beau Scott Disick at a boxing match Tuesday in L.A. — with all money going to charity.

"We actually got to see the people that we're fighting the other day and Kim's person scares me," Khloe, 25, told KIIS-FM's Ryan Seacrest Monday. "She's jacked."

While Khloe was tight-lipped about her own opponent, the newlywed — who swapped vows with L.A. Laker Lamar Odom Sept. 27 — says she's worried for sis Kourtney's beau.

"I hope Scott wins, or it's going to be embarrassing," she says of dad-to-be Disick, 27. "He isn't the best in the ring. He's really concerned about his hair!"

Proceeds from the Kardashian Charity Knock Out — to be taped for an upcoming episode of Keeping Up With the Kardashians — will benefit the Dream Foundation.
