Bristol told UsMagazine,
I just wanted to do it because it's so fun. It's positive and it's a good competition. I wanted to step outside my comfort zone and have a good time.
As for her #1 fan... Mom, Sarah Palin. Bristol says,
She's always been my No. 1 fan. Of course, she'll be down here [cheering me on].
The dancer she's is most worried about are Dirty Dancing's Jennifer Grey and singer Brandy because "they both have some dance experience," she says.
Do you think Bristol stands a chance?
