Kourtney Kardashian Celebrates Her Birthday in a Bikini

Kourtney Kardashian and Scott Disick traveled south of the border last week for a Mexican retreat. The eldest Kardashian sister lounged on a chair in a pink Mara Hoffman bikini on Friday while chatting with Scott and a group of girlfriends and was back in a blue bikini on Saturday. While it looked like she had left her children, Penelope and Mason, in her mother's hands for the beginning of the trip, Mason and Penelope joined her over the weekend. There was plenty to celebrate since Kourtney turned 35 on Friday and Easter fell on Sunday.
