While accepting the Desert Palm Achievement Award at the film festival, the pregnant actress couldn't help but talk about fiancé Benjamin Millepied, the choreographer who she met while making Black Swan.
As Benjamin, 33, looked on from the audience, the 29-year-old Closer star appeared emotional as she thanked her fiancé, who 'partnered me in the movie and who now partners me in life.'
A source told UsMagazine.com that it was 'seductive' watching the pair fall in love on the set of the movie.
An insider told the entertainment website: "There was no way the attraction could be missed."
