The oldest son of Kourtney Kardashian and Scott Disick was out and about in LA with his famous mother when he aimed a bright yellow toy gun at photographers.

Wearing a grey sweatsuit and black beanie, the seven-year-old was clearly having some fun in front of the cameras, waving the plastic rifle around before heading into a class.

Kourtney, 37, was also dressed casually on the mother-son outing, wearing ripped jeans, a white tee and a pale pink coat.

The toy may have been one of Mason's Christmas gifts, after spending the holidays with his "modern family" in Aspen.

Along with Penelope, 4, and two-year-old Reign, Kourtney and the kids joined dad Scott Disick for some fun in the snow, skiing and ringing in the new year.

"Kourtney never stopped loving him, and they both feel they make great babies together," the source said. "Having another child with Scott will be a dream come true."

The couple originally called it quits in July 2015, after intimate photos of Scott surfaced with celebrity stylist Chloe Bartoli while on vacation in Monte Carlo.

Scott, 33, later apologized for his behavior on KUWTK, telling the famous family he regretted his decision.

"I've apologized to Kourtney a hundred times but I've never apologized to like all of you for letting all of you down and embarrassing you guys," he said through tears on the reality show. "I understand I need to help myself way before I can help her or my kids or whatever, but it's just been a really hard time going from like having all of you guys to having nobody, you know?"
