Ke$ha on Victorious Tonight

After Tori loses an old bet to her sister Trina, she is forced to be her assistant for an entire month. The only way to even the score is for Tori to do something really amazing for her. When an ice cream company launches a contest to win a personal performance by Ke$ha (who happens to be Trina's favorite musical artist), Tori and her friends set out to win the grand prize.
