Sienna Miller may not have been the impetus behind Diddy's split from longtime girlfriend and baby mama Kim Porter, but another woman apparently was.
Porter, who publicly and dramatically left the rapper earlier this year after more than a decade of on-off relations, has spoken out for the first time since the breakup, announcing that Diddy's diddling played a major part in their romantic demise.
The 36-year-old Porter tells Essence magazine that the rapper's philandering was one thing, but the fact that he fathered another child just months before she gave birth to now nine-month-old twin girls and took quite some time to fess up to the paternity, was another.
"As black women, we sacrifice," Porter says in a new interview. "We stand by our man, through thick and thin, through whatever. But if you feel like, 'Maybe I am getting the short end of the stick,' that's when a change has to take place."
Porter credits a girlfriend of hers for tipping her off to the long-rumored other woman, 31-year-old Atlantan Sarah Chapman, who has reportedly known the rap mogul for years and who gave birth to his child five months before Porter welcomed D'Lila Star and Jessie James.
"I wasn't even coming from the place of who, what, why. I laid low and did what women do: I did my background work, collected information. But I wasn't even on it like that, because I was pregnant, and what was bubbling inside me was a blessing from God. I couldn't let my energy be on that. I didn't have time for any drama, trauma and bulls--t."
There was no immediate comment from Diddy on any extracurricular daddy doings.
Still, Porter says it damaged the relationship more that she didn't find out directly from the artist otherwise known as Sean Combs.
"I would have preferred to find out from him, because that's a man. I know it's hard for anyone to say to their significant other, 'I've gotten into some s--t, and I got a baby on the way.' But men do get caught up in things; I'm not naive to that. Still, there's a right way and a wrong way to handle it. Because most of all, we were friends. Even if I couldn't have understood it as a woman, I would have understood it as a friend."
Porter tells the magazine Diddy eventually did own up to the wayward paternity, though only after tabloids had picked up on the rumors and long after the twins' Dec. 21 birth.
"He told me he may have gotten himself into a situation, and he may have fathered another child outside the relationship, and I said, 'Really? Well, I already knew that. I'm glad you decided to be a man.' "
For Porter, it was too little, too late.
"I was like, 'Dude, this is so whack I can't even respect you right now.' And for me, once the respect is gone, I'm not even listening to you."
It was after the revelation that she decided to jump romantic ship, packing up the Pufflings and her belongings while the rapper was out of town and moving from Manhattan to Los Angeles.
"I wanted to be dramatic," she continues. "I wanted him to know I wasn't breaking up with him for two weeks—or maybe leaving for two days. If I pack up everything—twins and all—it means I'm out! Puffy's an action person, not a talk person. So, I had to have an action. Telling him, 'Babe, I'm leaving...' was not gonna do it."
As for reports that another main problem with their nearly 12-year relationship was the lack of a ring-finger bauble, Porter shoots down the rumors that an engagement would've made things different.
"Do you know how many rings I have? I don't even have enough fingers. That's not why I left...I don't want to get married, but because he's not ready to get married. When I get married, I want to stay married. I want both parties to be on the same page at the same time and to leave a certain type of behavior behind. That's a commitment I don't think he's ready for."
