The family outing comes just days after news broke that Carey and boyfriend Bryan Tanaka had called it quits. A source told ET that the relationship had been "tapering off" for some time, but really started to crumble on St. Patrick's Day.
While dining at Los Angeles hotspot Catch, Carey was overheard telling the wait staff that she's still very close to her ex-husband -- and father of her children -- Nick Cannon, the source said.
"Tanaka was extremely jealous, upset and he stormed off [from] the table," the source claims. "Tanaka has long been jealous with Mariah’s close relationship with Nick Cannon."
Tanaka returned to the table, an eyewitness at Catch told ET, but not without some drama.
"Mariah saw him come back and openly flirt with a female waitress, which really upset Mariah. She was furious," the eyewitness says. "He was ordering lots of food, drinks and putting it on Mariah's tab."
