Kourtney Kardashian's jealous boyfriend shades her bikini Instagram photo

Kourtney Kardashian's boyfriend Younes Bendjima appears to have let his jealousy get the better of him on Instagram.

In a now-deleted comment, the 25-year-old lashed out at Kourtney's skin-baring snap, according to TMZ.

"That's what you need to show to get likes?" he wrote, under a snap of the Keeping Up With The Kardashians star in a skimpy booty-baring bikini.

Fans were quick to respond, with many siding with Younes' harsh observation.

"Your man called you out. Ha! You're too old to be doing this. Go be a mom and do mom things," one commenter said. 

"At least your boyfriend has more class than you, maybe it will eventually rub off on you," wrote another.

Some fans speculated as to why Younes took issue with the post.

"Younes is not happy, he won't last with her. He is a Muslim man and he wants her covered up," one comment read.

Kourtney has reportedly been dating the model, who is 14 years her junior, since October last year.

The couple got together shortly after she officially split from Scott Disick, the father of her three children.
