Sienna Miller Rumored to Be Cause of Diddy Break Up with Baby Momma Porter

If the Daily Mail is to be believed (and why wouldn’t they be) Diddy’s "friendship" with Sienna Miller led to the latest off-again of his longtime, intermittent relationship with the mother of three of his four children, Kim Porter.

Apparently, Diddy’s most recent gallivanting with the skanky Brit was the last straw for Porter, who gave birth to the couple’s twins in December.

Rumours of a rift between the two began circulating earlier this year when, right after the birth of the twins, Combs was seen out partying with Sienna till the early hours of the morning.

After the Factory Girl premiere the actress was spotted sneaking into her hotel at 9am in the morning with the rap star in tow.

But Diddy, told photographers at the hotel: "Man, I was just being a gentleman and dropping her off.

"Yeah, we all hang out together but there’s no more to it than that."

However, in the week prior to that they were seen cosying up after meeting at a film festival in Utah.

The friendship between Combs and Miller was rekindled last weekend when he arrived in London to perform in the Concert for Diana at Wembley Arena.

We’re guessing that January was pretty busy for Porter, and that she delayed her departure for a more manageable time. That in her postpartum hormonal state she resisted tracking Miller down and strangling her is a real testament to Porter’s self control.

If we had just delivered number 3 and number 4, out of wedlock for Thug Cheaty and heard that lame excuse about being a "gentleman" we would be on trial for double murder right about now. Or hiding out in Mexico learning Spanish and drinking mucho Pinas. Ole!
