Here's everything you need to know about Kim Porter and her relationship with Sean Combs:
How many children does Kim Porter have with Sean Combs?
The pair have had a turbulent relationship ever since they first started dating in 1994.
They welcomed their first son together, Christian Casey Combs, in 1998 but split soon afterwards.
In 1999, Combs famously began dating Jennifer Lopez but they ended things in 2001 amid reports of Diddy's rumoured infidelity.
Porter and Combs later reconciled and welcomed twins D'Lila and Jessie in 2006.
Things weren't to last, though, and Porter dramatically split with Diddy again in 2007 after she found out he had fathered a child with another woman, Sarah Chapman, and that that child was born before the twins.
Talking about their final split, Porter told Essence in 2009: "I wanted to be dramatic. 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."
Despite being separated, the pair remained close and often holidayed and spent Christmas together.
"We're still friends," she said at the time. "I'm the person he can tell his inner most thoughts to and he's that person for me. He still calls me every day and we still talk."
In 2017, Porter shared a photo of herself with her twin daughters, Combs and his ex Chapman and their daughter Chance with the caption: "Now we HERE #BlendedFamily #cantstopwontstop."
Combs is also father to 24-year-old Justin with ex-girlfriend Misa Hylton-Brim.
