Kim Porter and the Diddy

Kim Porter has spoken publicly for the first time about her split from P.Diddy. Porter - who has three children with Diddy - says her decision to end her 10-year on/off relationship with the music mogul was in everybody's "best interests". She told TV show 'Entertainment Tonight': "After 10 years, I have decided to end my on-again/off-again relationship with Sean 'Diddy' Combs."In ending this relationship, I made a decision that was in the best interests of myself, Sean and our family. I look forward to moving on with my life and my career, and wish him prosperity, health and happiness in life and in love. We will remain friends and committed parents to our children."Last week, the model-and-actress was said to have moved out of the rapper's apartment, vowing never to return. Porter has now bought a luxury Beverly Hills home for her and the couple's children, 10-year-old Christian, and seven-month-old twins D'Lila and Jessie. She also has a son with former lover musician Al B. Sure. The couple's split comes amid rumors the hip-hop star has been romancing actress Sienna Miller. However, Sienna's representative has denied the allegations, saying:"Reports of Sienna being linked with P. Diddy are categorically untrue".
