Branson wants to take Winslet to visit the shipping wreck
Branson, who's very good friends with the Oscar winner, is planning to go on a diving trip to visit the Titanic in the North Atlantic.
"It is something I am very keen to do" he said to the Mail on Sunday "I'm deadly serious about this and I would love to invite Kate to come with me".
"Wouldn't it be something if the star of Titanic really got to go down to the real ship?" added Branson "I'm going to talk to her but I'm sure it's an opportunity she will jump at."
Winslet is said to be dating Richard Branson's nephew, Ned Rock.
