Ke$ha Rocks Out At Shepherd's Bush Empire

Ke$ha performs at Shepherd’s Bush Empire on Tuesday (December 14) in London, England.

Last week, Billboard crowned the 23-year-old pop star, the Top New Artist of the Year. Ke$ha is the first woman to ever have a first charting single become the top song of the year since they began doing round-ups over 70 years ago (for “TiK ToK,” which spent nine weeks at No. 1 on the weekly Hot 100 list.)

The year-end Top Artists list ranks the best-performing acts of the year derived from activity on two charts: the Billboard 200 albums tally and the Billboard Hot 100 singles list. Congrats Ke$ha!
