Puff Daddy went on Live with his mom this weekend.

The session is notable because his sidepiece Jesse Mae was briefly caught in the background of the stream.

While that should anger Diddy's girlfriend Yung Miami, there is another rapper who might take issues with the IG session.

During the stream Puff's mom Jacine Combs issued a stern warning for Diddy's old Bad Boy artist Ma$e.

"Shout out to the LOX, Ma$e, Biggie, Busta," the Diddler said. "I’m talking about everybody that’s on the ..."

"Ma$e," his mom interrupted, incredulously.

“Yeah, we still love Ma$e," Puff claimed.

"Don’t mess with my son," Janice made clear to Ma$e."

Earlier this year, Ma$e -- who has a long-standing dispute with Puffy over his masters -- rapped this about his former boss.

“Yeah, I’m just a Harlem n*gga repping down a Vegas strip with my own Suge/You from Mt. Vernon, n*gga, go & rep your own hood,” Mase raps on “Oracle 2: The Legend of Mason Betha.". “I’m not hating on your Billi worth/Right now, I’m only saying what you really work/You ain’t no architect/You just a n*gga who know how to market death.”

Mrs. Combs clearly didn't like that.
