Kourtney Kardashian Shows Off Her Super Slim Bikini Body
Kourtney Kardashian flaunted her post-baby bod in a skimpy bikini while hitting Miami Beach, Fla. on Saturday.
Kourtney, 31, welcomed her son Mason -- her first child -- last December. (Mason's dad is her boyfriend Scott Disick).
How did Kourtney do it? "Definitely breastfeeding helps," she said. "Everyone says that, but it's really true -- and it's just being a busy mom."
