For Her: What camera doesn't love this statuesque beauty? Against Her: Models don't have a great Dancing record.

For Her: Gray will add a nice dose of quirk to the dance floor. Against Her: It's not easy to be graceful with a 6-foot-tall frame.

For Her: Determination. She's been angling to get on the show for years. Now she has to show them what she's got. Against Her: If her dancing on Sabrina, the Teenage Witch is any indication, she may need a lot of help. Then again, that was acting, right?

For Her: She did the "Cell Block Tango" in the Oscar-winning musical Chicago. She also knows how to dance with poles (no, not like that). Against Her: She may be the ringer to end all ringers.

For Him: As a comedian, he will have a sense of humor about the whole thing. Against Him: His pops, George Hamilton, didn't fare too well on Season 2. Like father, like son?

For Him: He can get tips from his Dallas Cowboys "Triplet" and Season 3 winner Emmitt Smith. Against Him: No football star has been able to match Smith's success.

For Him: As a trained martial artist, he will have the moves... to kick everyone's ass. And he'll be this season's ab candy. Against Him: Len Goodman will be having none of this.

For Him: The consummate entertainer can work a camera. And he's got Osmond Nation behind him. Against Him: Osmond Nation.

For Her: Clean and sober, she's this season's Steve-O. Besides, being born into a musical family, she must have some rhythm. Against Her: She says she doesn't care if she wins. That's not going to fly, Kel.

For Her: She can solicit dance advice from her BFF Madonna. Not that she needs her help: Mazar is a former B-girl. Against Her: She's not what you'd call "ladylike."

For Him: The Iceman always comes to play. Plus, we're dying to see some mixed martial arts dancing. Against Him: What's the UFC-Dancing crossover audience like? Yeah, we figured.

For Her: Being an Olympic champion. Duh. As a pro swimmer, she's flexible, competitive and disciplined to train for hours on end. Against Her: Nothing. She's perfect.

For Her: Viewers cheered her on as she cursed out Terrell Owens on The Superstars. Against Her: Some thought she went overboard with the T.O.-chastising (who would've guessed?). Also, in the Battle of Models, Ireland wins.

For Him: This pro snowboarder knows from flashy tricks. Plus, anyone who can bust out back-to-back 1080s, a frontside 720, a tweaked-out Method and a cab 900 can't have two left feet. Against Him: At 5-feet-5-inches-tall, he's on the shorter side.

For Him: He's been performing all his life and can borrow from the Backstreet Boys choreography playbook. Against Him: He doesn't fit the typical "Corruptible Youth" profile, having two-timed Hilary Duff and Lindsay Lohan, been busted for marijuana and reportedly hooked up with Paris Hilton after she broke up with big bro Nick.

For Him: What's up, conservative flyover-state viewers? Against Him: Liberals.
