Kourtney Kardashian flashed onlookers when she was twirled around by Khloe, blowing up her short skirt and showing off her derriere in the process.

The mother-of-two was playing around with her younger sister on the balcony of Miami’s Eden Roc Hotel on Wednesday when she showed a little more than expected.

Kourtney and Khloe kardashian- who are in town with their sibling Kim filming their new reality show – were doing a 50’s-style dance number.

The sisters were laughing and having a great time when the mishap occurred.

Kourtney Kardashian, who was wearing a white and blue-print blouse and short canary-yellow circle skirt, was being pulled into a twirl by a taller Khloe when the wind picked up and blew up her skirt.

Underneath she revealed a very skimpy pair of underwear.

In the famous comedy The Seven Year Itch, Marilyn Monroe cools off from the summer heat by letting her skirt fly up over a vent above the subway.

Marilyn Monroe’s subway scene is perhaps her most memorable, even to this day.

Kim Kardashian, 31, and eldest sister Kourtney, 33, are currently living in Miami shooting scenes for their new reality show, Kim and Kourtney Take Miami, of which Khloe, 28, is undoubtedly a part of too.
