Pop star Pink has set an Oct. 28 release for her as-yet-untitled fifth album. The LaFace/Zomba set is led by the single "So What," which will hit radio early next month and digital outlets shortly thereafter.

The song was co-written by Pink and produced by Max Martin, who was behind the artist's prior hits "Who Knew" and "U + Ur Hand." The video will be directed by Dave Meyers, who previously worked with Pink on clips for "U + Ur Hand" and "Stupid Girls."

Pink will promote the new video during stints as the guest commentator on MTV's "FNMTV" on Friday (July 25) and Aug. 1.

Other album collaborators include Butch Walker, Billy Mann and EG White. The new set is the follow-up to 2006's "I'm Not Dead," which has sold 1.3 million copies in the United States, according to Nielsen SoundScan.
