The pair who have been dating for five years are reported to have been engaged in a shouting match inside their car on Wednesday, August 17, 2016, after the singer revealed her intentions to end the relationship.
TMZ reports that Diddy had immediately grabbed Cassie's phone, and exited the car, scrolling through it in the possible hopes of finding the reason for her plans to end their relationship.
Cassie had gone home with the driver, where she called her mother, informing her of the fight and the fact that Diddy had seized her phone.
Diddy reportedly returned the phone as soon as he got home, leaving shortly after.
Cassie's concerned mum called the cops who showed up at the 29-year-old's home. she explained that the phone had been returned, after which they left but not before a domestic incident report was filed.
Sources close to the pair reveal that this is hardly the first time they have split up like this, which suggests that they might be on a break of some sort.
