April 21 - US pop star Prince, the 57-year-old whose hits included "Purple Rain" and "Kiss," was found unresponsive on Thursday at his Minnesota home and was later declared dead, US media reports said.

Celebrity website TMZ, citing sources close to the star, was first to report Prince's death at the home in Paisley Park, in a Minneapolis suburb. The Associated Press later cited his publicist as confirming the report.

Representatives for the singer did not immediately respond to Reuters' requests for comment. The local medical examiner declined to comment.

He first found fame in the late 1970s and over the next three decades became known as one of the most inventive and eccentric forces in American pop music.

Prince, an intensely private person, sold more than 100 million records during his career, won seven Grammy awards and was inducted into the Rock and Roll Hall of Fame in 2004.

In 2007, he played the Super Bowl in one of the most celebrated such performances.

His most recent album, "HITnRUN: Phase Two" was released in December 2015, and the artist had been on tour in the United States as recently as last week.

In 1993, Prince legally changed his name to an unpronounceable symbol, but later changed it back again.
