So What! Pink's At Number One 9/18/08

Pop star Pink has scored her first solo number one on the U.S. pop charts with angry love/hate anthem SO WHAT. The singer previously topped the chart with a 2001 remake of Labelle's Lady Marmalade with Christina Aguilera, Mya and Lil' Kim.

So What replaces T.I.'s Whatever You Like, which falls to two on the new Billboard chart. Rihanna's Disturbia stays put at three and M.I.A.'s Paper Planes climbs to four.

Jay-Z scores the countdown's highest debut at five with Swagga Like Us. The track, from Jay-Z's new Blueprint 3 album, features T.I., Kanye West and Lil Wayne.
