Food trucks, cake and more

Mason Disick’s famous family went all out for his lavish bar mitzvah.

The night celebrating Kourtney Kardashian and Scott Disick’s eldest child – who turned 13 on Dec. 14 – included a massive cake, group dancing and wild fashion choices.

New video obtained by TMZ shows Mason’s 8-year-old brother, Reign, who shares a birthday with the bar mitzvah boy, being hoisted up onto partygoers’ shoulders at the Offsunset lounge in West Hollywood, Calif., on Saturday.

However, Mason was still the star of the celebration as he was presented with a giant, two-tier cake decorated with Star of David symbols and topped with celebratory sparklers as the crowd sang him “Happy Birthday.”

He also danced for the crowd as the DJ played Ayo & Teo’s hit song “Rolex.”

Scott, 39, was seen proudly watching from across the room, which was decked out with hundreds of silver-mirrored balloons and several signs shaped like scrolls that read, “Mason’s Bar Mitzvah.”

Food trucks were also parked outside the party, with one serving Van Leeuwen Ice Cream, a second handing out Raising Cane’s Chicken Fingers and one more giving out sweets from The Churro Man Truck.

Meanwhile, Kourtney, 43, was also in attendance to celebrate her son’s big day and wore a black suit that showed off her toned abs.

While her husband, Travis Barker, wasn’t photographed at the fête, her sisters arrived in full force to show their support.

Kim Kardashian rocked leather pants and a T-shirt, while Khloé Kardashian opted for a black bodysuit and a big cross necklace. Meanwhile, Kylie Jenner stunned in a skin-tight leather dress and Kendall Jenner looked chic in a lace and satin dress and a diamond necklace.

Their mom, Kris Jenner, opted for a more conservative look in a black pantsuit adorned with lace flowers.

Kourtney took to Instagram to celebrate her two sons’ birthday earlier in the week.

“December 14th… one of the best days of my life, twice and forever. my birthday boys ❤️❤️,” she wrote on Instagram along with an old photo of the two brothers.

Scott and Kourtney share three kids together: Mason, Reign, and 10-year-old daughter Penelope.

The pair split up in 2015 but continue to co-parent their children.

Kourtney has since moved on with Barker, marrying the Blink-182 rocker with a surprise Las Vegas wedding in April. She and Barker, 47, continued to celebrate their marriage with two more weddings: one in Santa Barbara in May and another lavish celebration in Italy that same month.

Meanwhile, Scott is seemingly single. He dated Sofia Richie on and off from May 2017 to August 2020 and was romantically linked to Amelia Gray Hamlin from October 2020 to September 2021.
