Diddy Reunites with Cassie After Kim Porter's Death

Kim Porter’s tragic death has brought Diddy and Cassie back together.

One day after his ex’s passing, Sean “Diddy” Combs was seen reuniting with Cassie following the couple’s recent split.

According to PEOPLE, the hip-hop mogul was spotted leaving The Movement Institute in Los Angeles, his first public appearance since Porter’s death on Thursday (Nov. 15).

The 49-year-old Combs was dressed in red shorts and a black hoodie that read “Do the Right Thing,” while Cassie wore all black.

The cause of Porter’s death is unknown at this time. Authorities were called to the actress-model’s home in Toluca Lake, Calif. home after a 911 call reported “a patient in cardiac arrest.” Porter was reportedly battling pneumonia in the weeks prior to her death.

Diddy and Porter began dating in 1994 and split in 2007. They had three children together–son Christian, 20, and 11-year-old twin daughters D’Lila Star and Jessie James. Diddy also considers Porter’s eldest child Quincy, 27, a son.

“Diddy is devastated and shocked,” a source told PEOPLE. “He and Kim were still very close friends and co-parents even though their romantic relationship didn’t work.”

In October, Diddy and Cassie confirmed their breakup after reportedly being separated for months. “They are indeed no longer together and haven’t been for months,” a rep for Cassie told Love B. Scott.
