Kendall slips in bikini for having fun with frisbee!

Distressing though this may be for their children, at least they have the best of both worlds when it comes to L.A. living.

Kendall seemed pretty content as she played frisbee with friends on the sand in front of her Olympian father's home in a sporty two-piece. Kylie was earlier pictured with her new BFF, Hailey Baldwin, 17, also at the house.Earlier in the day, Kendall threw on a cover up dress to head to lunch in Malibu.
