Amanda Seyfried used a popsicle when pretending to give Peter Sarsgaard oral sex.

The blonde actress had to film the raunchy scenes with the actor in movie Lovelace - a biopic of infamous porn actress Linda Lovelace - and in order to make the sexual acts look convincing, she decided to use the icy treat as a prop.

"We were doing a sex scene where I was supposed to be going down on Peter Sarsgaard. We used a popsicle, and I had my arms covering the popsicle. It was footage that he was going to show the Deep Throat guy, to get her into the movie, to get her cast. I was laughing hysterically throughout. I couldn't stop laughing."

Amanda also says she's become more realistic as her career goes on as she knows Hollywood is a tough place to work in. Speaking about her first big movie, Mean Girls, she told Vanity Fair, "Back then I thought every movie that was made found an audience and things were all stars and butterflies, before I developed a relationship with this world."
