"She's my number one cheerleader and I can't wait for her to come watch the performances and just see me in a whole new light," says the 19-year-old, who'll be competing on the ABC show with pro Mark Ballas, beginning Monday (8 p.m. ET).
And Palin, who recently spoke to BallroomFantasy.com, appears to be in good hands with Ballas, a two-time DWTS champ. "[He's] an amazing teacher and an awesome coach," she says, adding that he's trained her to use "muscles that I've never used before."
And Alaska's former first daughter has her work cut out for her. "She's the prime example of what this show is all about. She's never danced a day in her life. She's a complete fish out of water," Ballas told the site.
"Learning the steps and learning to choreograph it and have rhythm to everything," says Palin, "is extremely challenging."
