Kourtney Kardashian dons mom jeans at star-studded Malibu Chili Cook Off with ...

The Malibu Chili Cook Off attracted the gaze of multiple celebrities this weekend.

Among them was Kourtney Kardashian, who brought along the two elder of her three children - eight-year-old Mason and six-year-old Penelope.

Kourtney, 39, got back in touch with a bit of childlike glee, throwing her arms up and beaming as she went down a slide alongside little Mason.

Clasping on a cross, the firstborn child of Kris Jenner emphasized her enviably toned figure in a fitted white tank top and a skintight pair of charcoal jeans with a high rise.

Kourtney, whose younger and more famous sister once dismissed her as 'the least exciting to look at' in the family, gave Penelope a piggyback ride.

Along with her children, Kourtney brought along her 44-year-old pal Larsa Pippen, the second wife of erstwhile NBA player Scottie Pippen.

Larsa slid herself into a white tank top and a matching pair of high-rise shorts, adding a splash of color to the ensemble with lime green shades.

She and Kourtney gleefully rode the canary yellow slide together, smiling radiantly as they plummeted down toward the ground.

The duo were also seen enjoying a ride on some high elevation swings - though the view seemed insufficient entertainment for Kourtney, who checked her phone. 

Among the other Cook Off attendees were Kourtney's 22-year-old half-sister, international supermodel Kendall Jenner, as well as actor Orlando Bloom.
