Kourtney Kardashian Gets Completely Naked And Kylie Jenner Admits She's Jealous!


We got a sneak peek of next week's episode for KUWTK, which has the famous family vacationing in Costa Rica for Kourtney's birthday. This is where Kourtney gets in her birthday suit for a photo shoot in the pool. (She looks HOT, but that's always.)

Kourtney is goals, she's 38... with three kids and a MILF! 

GO KOURTNEY GO!

Her younger sister, Kylie Jenner, admits she's "jealous," after wrestling her to the ground.. of course! We love these sisters.
