She's not going to let a man tell her what to do!

Kourtney Kardashian rocked a plaid crop top with jeans to film Keeping Up with the Kardashians yesterday, and her boyfriend Younes Bendjima dropped by to keep his lady company while she worked, so he must be OK with her racy outfit choices now.

The 24-year-old model caused quite the stir when he dissed her on Instagram for posting a pic of herself in a thong bikini, and it went over like a lead balloon.

"Kourtney doesn't appreciate Younes posting his feelings in a public forum and being impulsive. She's frustrated that he continues to get upset about it. She isn't going to stop doing what she's doing and feels like he needs to understand and deal with it," a source told E! News.

"Younes gets jealous and can be possessive of Kourtney. When she posts half naked pictures, he gets very upset. He wants her for himself and doesn't want to share her with the world. Kourtney has explained its part of her job and it's not going to change. But it still makes him uncomfortable and upset. He overreacted and put up a comment without thinking it through. Then he realized what he did made it even worse. He was just not thinking in the moment and got emotional," the source added.

Side note - he's living the high life whipping around in Kourt's fancy wheels!
