The parents to Mason and Penelope traveled south of the border with a group of friends, where they were snapped enjoying the glorious weather on Friday, April 18. A source tells Us Weekly the trip, which was arranged by Disick, was kept a secret from the birthday girl.
Disick shared a cute Instagram snapshot Friday, hanging out on a luxurious private aircraft with Kardashian. "Happy birthday," Disick wrote beside the pic, with his arm around his pretty lady.
Though it remains unclear if the couple's tots joined them on the trip, they appeared to be in good spirits with their pals as they relaxed by their pool overlooking the ocean. The photographer who snapped these pics notes the group "enjoyed a few drinks."
Even sweeter than the surprise was Kardashian's hot bikini body, which she showed off in a multicolored, striped string bikini. Kardashian was photographed at the resort laughing with Disick and two girlfriends.
Khloe chimed in on her Instagram account, "Happy birthday to my twin soul, my spirit animal, my ace, my MILF, my boo, my best friend. I f--king love you so much! I could never explain how much I adore you.... You have to be around us to understand our bond. @kourtneykardash 35 never looked so good! Thank you for always being YOU!"
