For the bulk of 2018, serial (model) dater Leonardo DiCaprio, 44, has been linked to 21-year-old model and actress Camila Morrone.

It’s easy to cast off Morrone as another fling in the Oscar winner’s 20-something model-filled black book, but according to reports, things are changing for Hollywood’s most eligible bachelor.

A source told Us that DiCaprio is ready to settle down with his barely legal gf — marriage, kids, the works! But another (perhaps more reliable, and certainly more believable) source told E! that a proposal is hardly forthcoming.

Though what began as a “very relaxed” relationship has evolved into something “more serious,” the source maintains that “marriage is definitely not a discussion yet.” Yet.

“It is getting more serious. They’ve been inseparable for the last year and are crazy about one another. They’ve gotten to know each other’s families and they love being together,” the insider explained. (It makes sense that DiCaprio would cozy up to Morrone’s stepdad, Al Pacino, as they both star in the upcoming thriller Once Upon a Time In Hollywood.) “He is very serious with Cami and has been for a while now, but marriage is not something that is on the horizon.”

After two-and-a-half decades of romancing sample sized women unable to sign for their own rental cars, it feels unlikely that DiCaprio will be changing his ways anytime soon. But hey, love works in mysterious ways.
