The reality TV stars were spotted soaking up the sun and swimming with their tiny tots on Saturday (20 July) during a mini family holiday to Miami, Florida. We're not jealous at all!
Kourtney dressed for the warm weather in an eye-catching neon yellow kaftan, which she later took off to reveal a matching coloured one-piece underneath that she wore to splash around in the pool.
Penelope was seen sitting on a sun lounger in a pretty white frock, but swiftly changed into a cute pink swimming costume to join her family in the water, while Mason rocked a pair of red swimming shorts similar to his dad's.
34-year-old Kourtney also posed poolside with Scott in a black swimsuit, which she wore for a sweet snap that was posted on her Instagram page yesterday (21 July).
The petite brunette is obviously no stranger to the sunny perks of Miami, since she and her sisters Kim and Khloe spent several months in the city to film their spin off reality TV series, in which they set up their Miami based clothing store.
During her visit on this occasion, Kourtney has not only spent quality time with her adorable family, but she also met up with close friend and fellow reality TV star, Larsa Pippen, as well as enjoying a Wildfox fashion show one evening with Scott.
For the Wildfox show, the eldest Kardashian wore a gorgeous vintage Versace dress with Betty Boop printed on the front. Very cool!
