Dicaprio Back with His Model

Hunky star Leonardo DiCaprio is enjoying his reunion with supermodel lover Gisele Bundchen - and insiders predict things are getting very serious between them.

And despite their previously rocky romance, this time the couple could be heading up the aisle.

The Titanic star and gorgeous Gisele looked very in love as they walked together to his mother's house in Los Angeles last week.

An insider says, "Leo and Gisele have had an on-off romance but now he's promising to marry her - and that's what she wants more than anything.

"Leo's suffered from a lack of commitment in the past but he's become totally smitten. They couldn't be happier together."

The lovestruck couple got back together after they bumped into each other at a party last month.

Gisele had reportedly ended their previous engagement because she was sick of Leo's tantrums.
