Leonardo DiCaprio's relationship with model Erin Heatherton is heating up and he may have "finally found his future wife".

The pair have only been dating for a short time but Leonardo, who has dated quite a few models in the past, apparently feels his search for a wife is over.

Star magazine claims that the actor is in love with the fact that Victoria's Secret star Erin has brains, beauty but is also very athletic.

"Up until now, Leo's ladies have been prissy, girly types," a source told the publication. "But when he met Erin he realised he had found not only a beautiful woman but a talented athlete as well

"Leo has been a real holdout when it comes to getting married. But with a girl like Erin, who has beauty, brains and can shoot hoops he may finally have found his future wife."

Erin almost had a career as a basketball star before she became a model. She and Leonardo love getting out into the fresh air and doing physical activities when they are together.

"Leo is a huge basketball fan. He has a full court at his home in LA and is a Lakers season ticket holder. Whenever he and Erin are together they are always doing something physical like hiking in nearby canyons, riding their mountain bikes or playing ball together," the insider added.
