Kourtney Kardashian Rocks A Yellow One-Piece Suit During Pool Day With Kids

Kourtney Kardashian is one hot mama and she doesn't have to rock a teeny weeny bikini to prove it.

Kourt and her family cooled down from the hot Miami sun in their hotel pool on Saturday. While the oldest Kardashian sister wore a bright yellow strapless bathing suit, little Penelope sported a bright pink ruffled number. Her beau Scott Disick and three-year-old Mason apparently didn't get the memo about neon hues. Scott and Mase wore matching red trunks. Like father, like son!

When Kourt wasn't carrying the one-year-old in the pool, she was relaxing with her well-behaved tot on lounge chairs. Sister Kim Kardashian and baby North West will be joining them in no time!
