Oh, this'll be interesting! Insiders tell Life & Style that two reality-show stars will be joining the cast of Dancing with the Stars: reality star Denise Richards and Jackass wild man Steve-O.

Life & Style has learned exclusively that Denise, 37, star of Denise Richards: It's Complicated, has already been prepping for her TV dancing debut. "She's super excited and has lost a few pounds to tone up and get in shape," an insider tells Life & Style. "She's ready and thinks she can go all the way!"

The London-born Steve-O (real name Stephen Glover), 34, became famous on the Jackass TV show (there were also two Jackass movies), which ran from 2000 to 2002. He specialized in stunts that involved gruesome forms of self-injury -- experience that could be helpful for Steve-O if he's paired with an aggressive partner!
