Romantic movie THE LAKE HOUSE has given Keanu Reeves the impetus to get down on a bended knee and propose to his girlfriend Claire Forlani, according to new US reports. After discovering how much newlywed pal and co-star Sandra Bullock loves married life to TV mechanic Jesse James, Reeves started talking candidly about his own marriage plans - and he means business. According to US tabloid the National Enquirer, Reeves has proposed to Meet Joe Black beauty Forlani after quietly dating the actress for three years. A source says, "Keanu didn't work up the nerve to propose until last week (ends16JUN06)." The actor reportedly flashed his famous smile and asked Forlani to marry him over dinner at celebrity chef Wolfgang Puck's new Hollywood restaurant Cut. And insiders claim the wedding venue, tentatively planned for late next year (07), will be the mansion the actor is renovating in the Hollywood Hills - just down the street from the estate Brad Pitt and Jennifer Aniston called home when they were married.
