Of the three, Grey's probably the only one immediately recognizable for her ability to dance. After all, she shot to fame playing Frances "Baby" Houseman in 1987's "Dirty Dancing" alongside Swayze. She also studied dancing at the Dalton School during her early years in New York City. But the breakneck pace of "DWTS" took a toll on Grey, 50, aggravating an old neck injury and prompting new knee problems. Still, with her pro partner Hough, she scored the season's first perfect score earlier this month. If Grey hadn't won it all, no one should have expected her to take it lightly. As Swayze famously said of her character in "Dirty Dancing," "Nobody puts Baby in a corner."
The youngest of the lot, Massey, 19, has a huge following among teens and tweens. He's best known for playing Cory Baxter in the Disney Channel sitcom "That's So Raven." Massey parlayed his role in that show into his own Disney series, "Cory in the House." He's also appeared in Disney Channel movies and recorded songs for Walt Disney Records. Making the jump from the Disney Channel to another Disney property, "DWTS," made sense, and Massey's made good on the show -- not only has he scored high marks from the judges and the viewers, he also dropped 18 pounds and shed 8 inches from his waist by shimmying and shaking.
Massey's enthusiasm has won him some high-profile fans outside of his usual demographic -- former "DWTS" contestants Lance Bass and Brandy Norwood said they wanted him to win. But if Massey had won the coveted mirror ball trophy, he said he was going to celebrate like a kid.
"I'm going to fill it up with Skittles, so everyone can come to my house and eat Skittles," he told "Entertainment Tonight" last week. "Taste the rainbow trophy!"
She doesn't dance. She doesn't sing. She doesn't act. But the one selling point 20-year-old Bristol Palin does possess is the ability to rile up her critics, whether as a spokeswoman for abstinence (remember that child she birthed in 2008?) or as a potential "DWTS" champion.
From the moment she cha-cha-ed onto the show to "Mama Told Me Not to Come," Bristol Palin has been this season's most talked about contestant. Beyond the voting controversy, her dance-floor style has been critiqued. Before her "Dancing" run, Bristol Palin told People magazine she would have "the most modest outfits for sure, because that's who I am." Indeed, her assortment of floor-length gowns has been a frequent topic of conversation among those who care about such things on the Internet.
