Sean Combs' ex-girlfriend KIM PORTER ended her 10-year romance with the hip-hop star because they "weren't on the same page" anymore. Model Porter walked out on Combs last month (Jul07) and is now hoping to claim maintenance for their children Christian, nine, and seven-month-old twin daughters D'Lila Star and Jessie James. She tells the U.S. edition of OK! magazine, "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). "In a relationship, it's important that the people are on the same page at the same time. And we weren't on the same page."
