Blake Lively dines with DiCaprio

However, the pair weren’t alone as a number of other people, including director Baz Luhrmann, also joined them at The Lion eatery. The group had met up strictly for work reasons, and were discussing a new movie project.

Leonardo – who is happily dating supermodel Bar Refaeli - has been cast as Jay Gatsby in a big screen adaptation of F. Scott Fitzgerald’s classic book The Great Gatsby. The film will be directed by Baz, and Blake is being considered for the role of Daisy Buchanan, who is the love interest of Gatsby.

“It was an eight person dinner,” a source told UsMagazine.com. “The director's whole crew was there. Leo and Blake didn’t leave together.”

Blake, 23, will have to see off some strong competition if she wants to win the role of Daisy. A host of Hollywood’s most beautiful actresses have already been linked to the character, including Keira Knightley, Natalie Portman, Scarlett Johansson and Michelle Williams.
