Jay-Z, Mariah Carey Break Hearts Together

Platinum rapper Jay-Z recently hooked up with R&B diva Mariah Carey, and the two superstars joined forces to record a song called "Heartbreaker" for Carey's next album, due out in November.

The song was produced by mix-tape star DJ Clue, who released his own solo debut, "The Professional," last year, and a remix of "Heartbreaker" was also cut with the help of Missy Elliott and Da Brat.

In other Jay-Z news, the rapper came forward in New York City on Wednesday to donate more than 50 boxes of his old clothing to two local charities for distribution to poor children and homeless people. He had cleaned out his closets after deciding to move out of his home in the Hamptons area of New York.
