No, nothing like a real-life hookup (Mulligan is a married woman!), but…
The two apparently make quite the impressive lovebirds in Baz Luhrmann's upcoming 3-D retelling of The Great Gatsby.
Sources tell me that DiCaprio, 37, and Mulligan, 26 deliver with their chemistry.
"Oh, you can see it and feel it," one source reports.
Another says that it's pure romance. In other words, you'll find no Fifty Shades of Gatsby here.
"I don't think you see more than passionate kisses," the source said. "It's classy and beautifully shot."
Warner Bros. Pictures presented a sneak peek at the movie—including some intimate moments between DiCaprio and Mulligan—during CinemaCon last month in Las Vegas.
Sharon Waxman of The Wrap wrote afterward, "[I]t's safe to predict that teenage girls will be lining up to see it."
The $125 million film is a reunion for DiCaprio and Luhrmann, who first worked together on 1996's Romeo + Juliet.
