Mason Disick is quickly outgrowing his famous mom Kourtney Kardashian.

The pair were spotted shopping together at Trader Joe’s in Calabasas, California, on Monday, November 18, in photos obtained by Page Six. Mason was pictured towering over the 45-year-old reality star as they shared a laugh while grabbing a shopping cart.

In the pics, both Mason and Kourtney were seen wearing oversized dark hoodies and black pants. They were joined by the Lemme founder’s 12-year-old daughter Penelope, who was still in her school uniform.

In photos of the outing, which also circulated on social media, fans couldn’t help but draw some comparisons between Mason and some other family members. “He looks like Rob,” noted one Instagram user, comparing the young teen to Kourtney’s younger brother, Rob Kardashian. Another agreed, adding, “Omg he looks like Rob and Scott!!!”

A third mentioned how grown up the young reality star looks, saying, “Omg lil Mase is all grown up.”

Kourtney shares Mason, Penelope, and 9-year-old son Reign with her longtime ex-partner Scott Disick. The couple, who were together from 2006 to 2015, have remained amicable as co-parents, with Scott still occasionally appearing on The Kardashians.

The Poosh founder is also mother to 1-year-old son Rocky, whom she shares with her husband, Travis Barker. The couple got married in April 2022, followed by a second wedding in Italy the next month. Despite the big celebration, Mason was seemingly not in attendance and was also absent from the Hulu special documenting their wedding, ‘Til Death Do Us Part: Kourtney & Travis.

Kourtney has shared in interviews that Mason doesn’t enjoy the public attention his family receives, telling the Not Skinny But Not Fat podcast in October 2022, “He doesn’t love it, and I want my kids to be kids.”

Despite that, Mason launched his own Instagram account in May, giving fans a rare glimpse at his life. Kourtney seemingly expressed some dissatisfaction with him joining the popular app, as she revealed in her Instagram Story that her “first baby is on insta,” and that she’s “not OK.”

While the account only has five photos – and he hasn’t posted since June – Mason has racked up a whopping 842K followers.
