Kourtney Kardashian accidentally flashes a pair of Spanx as she steps out for lunch in Miami

Kourtney Kardashian accidentally flashed a pair of Spanx when she stepped out for lunch in Miami on Sunday.

As she was dressed in a beach cover-up due to the warm weather, Kourtney Kardashian’s shapewear was visible when she turned to the side.

She’s not the only one who is a fan of Spanx as her sisters Kim and Khloe Kardashian have also been spotted using the underwear to smooth out any lumps and bumps.

Kourtney Kardashian, 33, in fact had flashed a similar pair of the nude underwear during a photo shoot last week.

The star had been getting set to pose in a green gown when a gust of wind caused her to have something of a Marilyn Monroe moment.

But it was a slightly less glamorous affair on Sunday as she headed for a meal with her partner Scott Disick and their two children Mason and Penelope.

Kourtney Kardashian carried little Penelope, who was shielded by a blanket, in a convertible car seat while Scott Disick took charge of 3-year-old Mason.

The reality star showed off her legs as she headed into the Florida eatery in her white and gold printed cover-up, which she teamed with matching flip flops and large round sunglasses.

The previous evening the happy couple had been seen going for a spin on Scott Disick’s black scooter.
