Leonardo Dicaprio is reportedly planning to propose to girlfriend Bar Refaeli.

The 'Inception' star - who has been dating the Israeli-born beauty for nearly five years - is said to have enlisted the help of his mother Irmelin to help him choose the perfect ring for the model.

A source said: "He is finally ready to settle down and make it official. Leo has told his closest friend that his mother has been helping him pick out an engagement ring for Bar."

The 35-year-old actor - who has previously dated a string of beauties, including supermodel Gisele Bundchen - is also planning to sell his Hollywood mansion and buy a house with Bar, 25.

The source said: "He's asked her to move in with him. Bar doesn't mind spending the night at his bachelor pad but she isn't comfortable living there all the time."

Meanwhile, a Canadian woman accused of attacking Leonardo with a beer bottle in 2005 was ordered by a judge on Wednesday (04.08.10) to stay at least 500 yards away from the star.

The incident left the Hollywood hunk needing a dozen stitches to his face and neck.
