The mother of three's toned bod was on full display as she hit the beach with friends in San José del Cabo, Mexico, on Friday.
Kardashian couldn't have looked more fit as she ran alongside the shore in a bright yellow bikini. At one point, she was about to take a dip in the ocean, but a lifeguard quickly approached her to tell her the waters were too rough for a swim.
Kardashian hasn't been shy about showing off exactly what her ex has been missing on her trip. On Saturday, she posted a series of pics to Instagram of herself in a purple metallic one-piece. "Sometimes I take all the shine," she captioned one shot, before striking a sexy pose along a rock wall.
Kardashian, 39, started dating Bendjima, 25, in 2016, but the two "recently broke up after [they] decided it wasn't going to work out," a source told ET. According to the source, Kardashian was the one to initiate the split.
"Near the end of the relationship, the two weren't getting along and the age difference ultimately played a part," the source added. "Younes is young, and although mature for his age, he and Kourtney are at different stages in their lives."
