Bristol Palin Dancing With The Stars leggings track jacket studio Hollywood

Sarah Palin's 20-year-old daughter Bristol was all smiles on her way into the studio to practice for the finale tomorrow night...

That's right - in case you forgot, Bristol Palin will compete for the Dancing With the Stars' mirror ball trophy on Monday with pro partner Mark Ballas.

Levi's babymama is up against 50-year-old Jennifer Grey (who will most likely win) and Disney star Kyle Massey. But is it possible Bristol will defy her critics and come in at number one?

The younger Palin has stayed on DWTS despite conspiracies about the Tea Party voting for her and claims her all-American appeal simply revolves around being "real." Will she surprise everyone but herself and win the top prize?

Meanwhile, a mysterious white powder and threatening letter was reportedly sent to Bristol at the Dancing With the Stars production office on Friday and caused a scare. Thankfully, the substance was determined to be talcum powder. But still! Not fun.

And Bristol herself was all smiles - see above - before practicing her dance moves yesterday afternoon. Whether you like her or not, she's definitely shown great courage in the face of such adversity!
