Inside Leonardo DiCaprio's 'very serious' relationship with Camila Morrone

Leonardo DiCaprio and his girlfriend, Camila Morrone, are getting "very serious."

Sources told Us Weekly that the couple, who have been dating for over a year now, has "talked about getting engaged" already, which would be a first for the notorious bachelor.

According to the insider, DiCaprio, 43, is "ready to have kids" with the 21-year-old model.

"Everyone is saying that marriage could be soon for them," the source added.

The new details echo what another source had previously disclosed to the outlet. Back in August, an insider said that "they're very in love" and the Oscar winner has "never loved a girl like this."

The unexpected news that DiCaprio could finally be headed down the aisle sometime next year may come as a surprise to a lot of fans, but it's apparently a non-negotiable for Morrone, who "wants to get married to him" before having children with the actor.

"She's very traditional in that way," an insider said. "She loves having little kids around and wants to have kids with Leo."

Morrone and DiCaprio were first romantically linked when they were photographed together in December of last year, but the Argentinian model, who's signed to IMG, actually met her boyfriend years before they were in a relationship -- 10 years, to be exact. The future couple, who are considered "old family friends," met through her stepfather, who just so happens to be legendary actor Al Pacino. Pacino and DiCaprio are longtime friends.
