Kim Porter, the mother of three of Diddy’s children, has insisted that there is nothing going on between the music mogul and Sienna Miller.

Diddy and Sienna were first linked at the start of the year and have met up at parties several times since then, and are currently believed to be holidaying together in Ibiza.

Kim told OK magazine that while Diddy, real name Sean Combs, did sleep around during their relationship, he’s “just friends” with Sienna and the actress “wasn’t the cause” of their split last month.

She explained: “I’d been in an on-again, off-again relationship with Mr Combs for about 10 years, and it came to a point where it was time for me to move on with my life.”

“I had invested a lot of time in that relationship, and it wasn’t going where it should have been going. So it was time to [end it].”

“I will never sit here and say that Puffy — or any man — is 100% faithful. I just don’t believe it. Some of you are, but I’m not going to sit here and say that I didn’t believe that he cheated on me. … I’m aware that he’s cheated. Has it affected the trust value? Yes, of course.”

“I have a history with him, and he’s the father of my children. Just because I love him, that doesn’t mean that we can be together. But I’ll always have love for him.”

Kim gave birth to the couple’s twin daughters in December last year and they also have a nine year old son, Christian.
