DiCaprio to propose to girlfriend?

London: Hollywood actor Leonardo DiCaprio is planning to pop up the question 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.

"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," femalefirst.co.uk quoted a source as saying.

"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," the source added.
