Jennifer Lopez and Drake's hot romance is starting to fizzle.

In Touch has exclusively learned the couple's relationship has hit a major roadblock, and it's because the 47-year-old "doesn't want kids," while the 30-year-old rapper wants to start a family in the near future.

According to a source close to the diva, Jennifer already has her pair — twins Emme and Max, 8 — so the idea of more babies isn't in the cards for her.

“She’s done having babies. But Drake’s at a point in his life where he wants it all," the source revealed. "A hot partner and the kids. It's causing problems."

The Views rapper could be fighting an uphill battle. Jennifer dated ex Casper Smart on-and-off for over five years without having another child. Prior to their split over the summer, it was reported the singer didn't see herself walking down the aisle with the backup dancer.

“[Casper]'s probably proposed at least five times. Frankly, she’s sick and tired of saying no,” a source previously revealed.

Drake and JLo sparked dating rumors mid-December, after the Toronto rapper shared a selfie alongside his love while attending her show, All I Have, in Las Vegas. Shortly after, their budding romance was seemingly confirmed after both shared matching Instagram photos, in which they shared a sweet hug.

As if the Instagram snaps weren't enough to convince fans they were indeed an item, PDA-filled videos were uploaded to social media just before the new year. The couple attended a Winter Wonderland-themed prom, and were spotted locking lips multiple times.

Last week, In Touch learned Drake's most-recent ex Rihanna claimed JLo was "desperate" for dating him, and even unfollowed her on Instagram shortly after their relationship was made public. She has since branded her former friend a "traitor."
