Billboard named Katy Perry its woman of the year, at Billboard's Women in Music event yesterday in New York City.
Perry released "Teenage Dream" in 2010, and the double platinum album sparked five No. 1 hits on the Billboard Hot 100 chart that spilled over to 2011.
She tied the record Michael Jackson set with "Thriller" for most hits from a single album.
She re-released the album this year, which launched two more hits and a top-grossing 3-D film.
