Rap mogul Sean "Diddy" Combs and his longtime girlfriend, model Kim Porter, who recently gave birth to twin girls, have broken up,  Combs' publicist confirmed on Tuesday.

The couple who also have a son together, Christian, was rumored to have split up last week, just months after they publicly proclaimed their love for one another in a cover story for Essence magazine, which described their on-off relationship.

Last week New York Post’s Page six reported that Porter moved out of the apartment she shared with Combs into a new home in Los Angeles with her children. Apparently, the cause of her move was Diddy’s rumored relationship with actress Sienna Miller. Diddy’s publicist denied the report.  

"There is literally nothing between them," the rep told People last week. A rep for Miller also said that "reports of Sienna being linked with P. Diddy are categorically untrue," People magazine reported.

Diddy,37, and Porter, 36, began dating in the ‘90s and called of their relationship for the first time in 1999. Although Porter said at that time that Combs simply fell for a "big booty and a smile" regarding his two-year relationship with Jennifer Lopez, and she knew he would be back, it didn’t stop her from going to trial and fighting for child support.

Porter gave birth to the couple’s twin daughters, D’Lila Star and Jessie James on December 21st and also has a teenage son, Quincy, from a previous relationship, while Combs has teenage son, Justin, with Misa Hylton-Brim.
