Here's Kourtney Kardashian in a bra having her butt grabbed by her crazy hot boyfriend

I guess this means these two are official!?

Scott Disick who!?!? Kourtney Kardashian just made things with boyfriend Younes Bendjima ~very~ official with a super steam Calvin Klein ad. In an Instagram photo, Kourtney, wearing a bra and sagging jeans, straddles Younes and takes a selfie. As you do. I know this is what I'm doing with my man as soon as he wakes up. It's like, first coffee, then I gotta straddle you for Instagram.

Anyway, the resulting shot is v v v hot and sexy:

I feel like Kourtney is the most undercover sexy of the Kardashian/Jenner krew — like, she's all "I'm a mom! I eat organic! Where's my minivan keys!" but then she's all, "Here I am half-naked on a jet ski dry humping my 24-year-old model boyfriend!!" I'm about it. Moms contain multitudes. Get it, Kourt!

Kourtney and Younes have been together for over a year after meeting in Paris around the time of Kim's robbery. Their relationship appears to be going from strength to strength. A source previously said: "It's definitely serious. No one thought their relationship would last this long, but Kourtney is very happy.

"Younes has met her kids. Kourtney's family really likes him. He is the opposite of Scott. He doesn't party, isn't flashy and really treats Kourtney with a lot of respect. It's obvious that he really cares about Kourtney."

You know who most likely isn't super stoked about this situation, though? One Mr. Lord Disick, Esq.

Rumors are that despite being "happy" in his new relationship with Sofia Richie, Scott is "insanely jealous" of Younes.

"Scott is still insanely jealous of Younes," a source said. "He just can't come to terms with the fact that Kourtney has found true happiness with someone else.

"Scott just never thought it would last this long with Younes or become so serious. Nobody really did."

The source added that he "can't deal with someone else having Kourtney. He can't control his emotions about it and lets it all out.

Love hurts, y'all!
