Former Keeping Up With Kardashians star Kourtney shared a photo of herself kneeling in front of the mirror in her walk-in wardrobe as she made the dig.
Kourtney, who recently confirmed her romance with Travis Barker, looked incredible in a red bra and thong set, from her sister Kim Kardashian’s SKIMS underwear range.
The two piece appears to be the same set Kourtney’s sisters Kim, 40, Kendall Jenner, 25, and Kylie Jenner, 23, modelled in a recent Valentine’s Day photoshoot Kim’s new SKIMS range.

Meanwhile a paper SKIMS shopping bag can be seen on the floor in the background of the snap, along with more lingerie sets, which are scattered around the walk-in wardrobe.
Kourtney flaunted her natural beauty in the photo as she wore a minimal amount of makeup and tied her long dark brown locks in a low plait.
As she shared the image with her 111million followers, Kourtney took a swipe at being left out from her sibling’s photoshoot.
She said: “Since I wasn’t invited to the sister shoot …”
Fans then flocked to stick up for Kourtney in the comments as one wrote: “You weren’t invited because you are the best sister…”
While another added: “UR THE HOTTEST SISTER QUEEN”. And a third said: “Because they know u stole the show” followed by a red heart emoji.
The dig appeared to be ignored by Kim, who recently reportedly filed for divorce from Kanye West, Kylie and Kendall who didn’t comment on the photo.
It comes months after Kourtney and Kim were embroiled in a shocking fight during Keeping Up With The Kardashians.
In shock scenes, Kim is seen launching a fist at her sister Kourtney after she appears to provoke her during an argument while they’re at home.
Mother-of-three Kourtney is seen throwing a bottle of coconut water at Kim, before getting into her face and asking: “You’ve got nothing to say?”
An enraged Kim is then seen snapping, telling her sibling: “Don’t ever come at me like that!” and then lunging at her.
Kourtney later announced her decision to leave KUWTK as she said: “I have decided to take a big step back from filming and really just pick and choose what I will allow cameras to follow.
“I think just now, when I have something that I find is interesting to film, or that I would feel excited to film, that I do that.”
