Is Kylie Jenner having what some would call a fling with one of her sister's ex-boyfriends? That's the new rumor as there's a report that says the controversial 18-year-old celebrity might be romancing Khloe Kardashian's ex-boyfriend, French Montana.

In fact, according to Star Magazine on Monday, the rapper was even spotted buying roses for Kylie during one of their romantic (but under the radar) date nights in Los Angeles.

The site also says that this isn't the first time the rumored couple have been spotted together. Back in April, there was a video circulating of Kylie bouncing on the rapper's lap, igniting rumors that they were indeed hooking up.

Since then, Kylie has broken up with her on-again, off-again boyfriend, Tyga, and is rumored to be dating another rapper, PartyNextDoor. In fact, she and French have insisted that they are just friends - and nothing else.

Kylie's relationship with Tyga sparked media controversy because the ex-couple began dating when she was just a minor at 17, while Tyga was 25. French Montana, who is 31, ended his relationship with Khloe back in 2014 after several months of dating.

So far, neither Kylie nor French has made any comments about their date or whether or not Khloe approves of their union.
