Combs and Porter began dating in the ’90s and split for good in 2007 after years of an on-and-off-again relationship. Together, the pair had three children: son Christian, 20, and 11-year-old twin daughters D’Lila Star and Jessie James. Additionally, Combs raised Porter’s eldest child Quincy, 27, and considers him a son.
The Bad Boy Records entrepreneur is also the father of two additional children — son Justin, 24, and daughter Chance, 12 — whom he shares with exes Misa Hylton-Brim and Sarah Chapman.

Meanwhile, Combs first met Ventura in the early 2000s after she was signed to his Bad Boy Records label. They were first linked together back in 2007 and have collaborated a few times together, including on his 2008 tune “Swagga Like Puff” and her 2009 song “Must Be Love.”
Then in 2012, five years after his split from Porter, Combs and Cassie went public with their relationship after years of speculation.
However, in October, PEOPLE confirmed the pair officially broke up, with a source sharing that “the decision was amicable and they remain friends.”
