Actress Sienna Miller has taken over Sean Combs (Diddy, P.Diddy, Puff Daddy, Puff) driving a wedge between him and longtime girlfriend Kim Porter.

According to reports in the U.S., 36-year-old Miss Porter has moved out of the couple’s New York apartment following rumours concerning the nature of Diddy and Miss Miller’s friendship.

News of the split comes just five days after the rapper and Miss Miller spent much of the evening flirting in the VIP area of London’s Paper nightclub after the Princess Diana memorial concert.

As Miss Miller walked into the club, she approached Diddy - real name Sean Combs - and flung her arms around him in a dramatic embrace before appearing to kiss him full on the lips.

They recently also enjoyed a romantic dinner together at the London restaurant Cipriani.

Six months ago, shortly after meeting Miss Miller at a film festival, the singer was caught sneaking into the actress’s Manhattan hotel at 9am following a night of clubbing.

Combs and Porter have three kids together including recently born twins within the last few months.
