“Pardon me, do you have any Grey Poupon…? @jetluxlife,” the reality star, 38, captioned the image eating a snack aboard their private jet.
Last month, papa Scott Disick, posted a photo of their 2-year-old son Reign also aboard a private jet.
The on-again-off-again couple – who are also parents to 7-year-old son Mason – appear to be off-again.
Famous in Love actress Bella Thorne, 19, recently dished on Disick’s hard partying.
“Scott is really nice, sweet, charming. I don’t drink, and he really drinks a lot. And it just ended up… I just wasn’t down. I was like, ‘I gotta leave,’” she told Complex of their recent fun times in France.
“We were [at Cannes] a day and a half before I was like I’m booking my flight and leaving,” the Disney Channel alum continued. “I love to go out and have fun, I love to f—ing dance, but I just don’t party hardcore like that and it was way too much for me. I was like, ‘Woah, this is not the way I live my life, bruh.’”
