Kim Kardashian is getting big-time compliments, and not just from anyone. The 40-year-old reality star and makeup mogul was stripped down to a stringy bikini ahead of the weekend, posting her Spring Break travels and making it one skimpy affair. Instagram uploads on Kim's account today showed her mind-blowing curves in a drenched and brown two-piece, with "The Blue Lagoon" photos also including the E! star's kids. Sister Kylie Jenner seemed to have spotted them, and she was going "MILF"in the comments.
