Kourtney Kardashian serves serious butt cleavage in Roberto Cavalli gown

Kourtney Kardashian may not be as known for flaunting her backside as sisters Kim, Khloe or Kylie, but the POOSH founder, 40, has no problem showing off her curves every once in a while, donning an open-back green gown cut low enough to see the reality star’s clearly exposed butt cleavage on Instagram.

“Cookin’ up positivi-tea,” wrote the mother of three Friday, as she is rocking the elegant sequin number in her kitchen while appearing to make tea on the stove. She later shared within her Instagram stories that the dress is actually a 2004 piece from Roberto Cavalli that she received from the Museum of Florence.

“Niiiiiceeeeee,” Adrienne Bailon of “The Real” wrote, with model Winnie Harlow adding, “Ouuu and her cup runneth overrrr 😍”

Sister Kim, 39, recently revealed her strained relationship with Kourtney manifested itself into the pair getting “a little violent” with each other on the upcoming season of “Keeping Up With the Kardashians.”

“It gets a lot worse before it gets better, but, you know, we’re a really close family,” Kim said. “It all works out. Our family’s never dealt with this before.”
