Sean Combs, 37, and Kim Porter, 36, have been dating off and on for ten years and have three children together: nine-year-old son Christian and six-month-old twin girls, D'Lila Star and Jessie James. Both Combs and Porter have children from previous relationships, thirteen-year-old Justin and teenager Quincy, respectively.

Today, Combs' rep confirms to Usmagazine.com that Porter has moved out of the Manhattan home the couple shared, and into a new place in Los Angeles.

The breakup comes after speculation that the rap mogul is seeing actress Sienna Miller, a rumor that Miller denies.

This is not the first time the couple has parted ways. In 1999, Combs dated Jennifer Lopez during a separation from Porter.
