French Montana is reportedly trying to win back ex-girlfriend Khloé Kardashian.

The Moroccan emcee took to his Instagram account on Feb. 12 to post a snapshot of himself with the "Keeping Up with the Kardashians" star leaning up against him, taken backstage at Kanye West's ROC Nation concert in New York City.

Kardashian then Instagrammed a photo showing off colorful roses and a diamond ring she presumably received from French on Valentine's Day. She wrote the following caption with the hashtag "#LuckyLady."

"He really wants to be exclusive with Khloé and is pulling out all the stops by sending her flowers, taking her on romantic nights out and buying her expensive gifts," a source revealed to HollywoodLife.com. "French is going all out to get Khloé.

"They dated last year, but he acted like a tool. He played around and didn't treat her like he should have," the source continued. "Khloé was still hung up on Lamar, so she didn't care. She never saw French as a long-term, serious relationship. They have had a friends-with-benefits relationship for months."

The source added the ex-couple's reconciliation is a great possibility: "It's starting to work, as Khloé is enjoying a man treating her so well. It makes her feel good, which is a nice change. She's also lonely and wants someone in her life."

Khloé Kardashian and French Montana recently reignited romance rumors, as they both attended the GQ x Armani Grammys after-party at the Hollywood Athletic Club on Feb. 8.

"French was on the side of the bar while Khloé chatted with the girls a foot or so away from the bar," an eyewitness told E! "Khloé was animated, laughing, and joking waving her hands in the air with the story she was telling.

"French had his arms folded on the bar leaning up against it chatting to his friends, and would look on to Khloé every once in a while."
