As their romance seems to be getting serious, French Montana shares a photo of Khloé Kardashian's butt as his new girlfriend is set to be featured in his upcoming music video for "Don't Panic."

The Moroccan emcee took to his Instagram account Thursday to post a close-up image of the "Keeping up with the Kardashians" star's derriere -- she is seen wearing a pair of booty-hugging shorts while lying on a bed. He captioned the photo "#asssscap."

Meanwhile, the 30-year-old reality star will appear in Montana's forthcoming video for "Don't Panic." The couple shared photos of themselves on the set.

In addition, the 29-year-old rapper recently revealed that he was hitting up a studio with Kardashian's brother-in-law, fellow rapper Kanye West. "Cooking up new Kanye x Montana prod. @foreign_tech #bang #CB," he captioned the Instagram video snippet.

In May, the "Ain't Worried About Nothin'" hit-maker discussed working with the "Yeezus" rapper. "Well, I just worked with Kanye. Me and Kanye was working yesterday. We did like four songs," he said to Complex magazine. "He produced and rapping. So, we still going back and forth. We even considering him producing my album. Well, Kanye actually was gonna sign me before I signed with Interscope. So, he was trying to sign me. I mean, since around that time we just build a great chemistry, a great relationship. And now he's working on his album. I'm working on my album. It's kinda like let's get together and make it happen ... . That's Kanye, man. One of the best to do it. You know what I'm saying? We just sit there and we talk about everything that's going on with hip-hop. This and that. And just come up with the best songs we can come up with."
