Amanda Seyfried has a crush on Justin Timberlake

London: Actress Amanda Seyfried says she has a crush on her `In Time` co-star Justin Timberlake and loved shooting intimate scenes together.

The 25-year-old, who will be seen with the singer-actor in the new sci-fi thriller, said she has had her eye on her handsome co-star - who recently reunited with girlfriend Jessica Biel, reported InStyle magazine. "Oh yeah of course I fancy Justin, I`ve known him for a while, he`s awesome. In the movie our characters have this instant connection. They immediately flirt and it`s awesome but then he takes her hostage because that`s the only way he sees to get out of this situation he`s in. And then she`s confused and their dynamic changes and it`s sexy and great," Seyfried said. The actress also said that Timberlake loves to sing on set, but she was too embarrassed to join in with him. "We didn`t have any sing-a-longs on set but he does sing a lot. I don`t sing when I`m around Justin, I`d be too embarrassed because he`s so talented. He was singing Cee Lo Green a lot," she added. PTI
