Video: Ke$ha Dishes About Prince, Miley and More
Kesha

Ke$ha has the first Hot 100 No. 1 of the new decade. Before "Tik Tok" made the L.A. woman a chart-topping star, Ke$ha stopped by Billboard HQ to tell us how she got to where she is, and gave us the scoop on how she snuck into Prince's house, met Flo Rida while wearing a dodgeball uniform, and got a gig writing songs for Miley Cyrus. She also reveald some of her other interesting "talents," such a yodelling and working a glitter canon.

We caught up with her again at Jingle Ball in New York this December -- just as "Tik Tok" crept to No. 3 and was poised for the top slot -- to find out her favorite moments of 2009 and to hear about her plans for 2010.
