"My woman, at the end of the day, you know, she ain't have a problem with it," he told Power 105.1’sThe Breakfast Club morning show on Friday.
Diddy paused to think for a few seconds before admitting that Cassie "had some questions," though he did tell the 29-year-old singer that J. Lo's current boyfriend, Casper Smart, was also with them.
"Me and Jennifer… people gonna be friends, man," he said. "People gonna grow, and, you know, any of my exes, they smile and they're happy to see me… and that's all that was about. And, you know, I answered the question and we kept it moving."
Diddy and Lopez dated from 1999 to 2001. In 2013, the 46-year-old American Idol judge claimed that their split was a result of infidelity.
"It was the first time I was with someone who wasn't faithful," Lopez told Vibe magazine. "I was in this relationship with Puff where I was totally crying, crazy and going nuts. It really took my whole life in a tailspin."
The "Booty" singer has been with Smart on-and-off since 2011, but following her relationship with Diddy, she married her back-up dancer, Cris Judd, in 2001. They divorced less than one year later, and she went on to date Ben Affleck, whom she was engaged to from 2002 to 2004, and marry singer Marc Anthony later in 2004. Her divorce from Anthony was finalized in 2014, and the pair share two children together, 8-year-old twins Emme and Max.
As for Diddy, he has been dating Cassie for five years, but the two have kept relationship very private, only appearing at a few events together.
