Kim Porter says she dumped Diddy.

"After 10 years, I have decided to end my on-again/off-again relationship with Sean `Diddy' Combs," Porter said in a statement Wednesday to syndicated entertainment TV show "The Insider."

"In ending this relationship, I made a decision that was in the best interest 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," the 35-year-old model said. "We will remain friends and committed parents to our children."

Porter and Combs have three children: a 9-year-old son, Christian, and 6-month-old twin daughters, D'Lila Star and Jessie James.

The 37-year-old rap mogul announced their split earlier this week.

He has another son, Justin, with ex-girlfriend Misa Hylton-Brim.
