Nothing brings the Kardashian-Jenner family together quite like a party.

Exes Kourtney Kardashian and Scott Disick reunited on Saturday to host a star-studded bar mitzvah party as son Mason turned 13.

The former couple were photographed arriving separately for the bash, held at the Offsunset lounge in West Hollywood, Calif.

It appears Kourtney, 43, attended the party without husband Travis Barker. She stunned in a black ensemble featuring trousers and a blouse with cutouts around her midsection.

Scott, who also rocked an all-black outfit, walked hand-in-hand with their youngest child, Reign Disick, who was celebrating his eighth birthday.

He and Mason were both born on Dec. 16, five years apart.

The guest of honor cut a casual figure as he opted for a black hoodie and a pair of baggy light wash jeans.

Mason’s aunties, however, went all out on the fashion front.

Kim Kardashian, 42, flaunted her toned abs in a cropped gray tee, which she paired with black leather pants adorned with sparkly black jewels.

She accessorized the look with a dazzling silver choker, a cross pendant necklace, a black handbag and pointy pumps, as she styled her honey locks in loose waves.

“The day has come where you’re taller [than] me now,” Kim captioned an Instagram Story in tribute to her eldest nephew.

“I just love who you are and I’m just so proud of you Mason. Welcome to your teenage years. Happy Birthday.”

The SKIMS mogul was photographed in front of the party’s Van Leeuwen Ice Cream truck as her mom, Kris Jenner, arrived in an all-black ensemble.

Meanwhile, Kylie Jenner looked glam in a latex bodycon dress, featuring one-shouldered detailing in a beige, tulle material.
