Robert Pattinson For Fifty Shades Of Grey Lead?

Speculation has been mounting thatRobert Pattinson is in line to appear as the male lead in the movie adaptation of Fifty Shades Of Grey.

Sam Taylor-Johnson was last week officially confirmed as the director for the project - and now R-Pattz has apparently been socialising with writer EL James.

E! News claims that the former Twilight star, 27, threw a birthday bash for filmmaker Nicholas Jarecki at his home in Los Feliz on Saturday - and that the author was among the guests.

Heather Graham, Moby, Michelle Rodriquez and Ellen Page are reported to have been among the other guests - and The Hangover star Graham spilled the beans about James' being there on Twitter.

She wrote: "A fun party looking at the super moon with Moby @thelittleidiot and EL James @E_L_James"

Other stars linked with the role of Christian Grey include Alex Pettfyer, Ian Somerhalder and Ryan Gosling.
