Amanda Seyfried Reveals the Movie That ‘F—ed’ Her

To actor Dominic Cooper's next love interest: By dating him, you're automatically going to get another celebrity in your life: his ex-girlfriend Amanda Seyfried

"We love each other," Seyfried tells Elle magazine of Cooper, whom she met on the set of "Mamma Mia!" and dated for two years before breaking up in 2010. "He'll always be in my life regardless of what his girlfriends or future wife think. I'm never going to be with a guy that can't deal with my friendship with him."

And, based on something else, er, interesting, she says in the interview, featured in the magazine's August issue, there was obviously sexual chemistry from the moment they met. "Everybody I've dated I've been sexually attracted to immediately," the former "Big Love" actress reveals. "Sparks don't grow — your vagina doesn't become more inclined to wanting someone just because you're around them."

Though the 27-year-old will admit there's someone new she’s attracted to these days, she won't admit who he is (surprise, surprise). "[He's] someone separate from my industry life- I've known him since he was 16 … I picture him as the father of my children all the time. But it is a fantasy right now."

As for her professional life, Seyfried is starring in one of the year's most risqué films, "Lovelace," a biopic out next month about '70s porn star Linda Lovelace, who famously starred in the controversial (yet wildly popular) adult film "Deep Throat." And yes, as expected, Seyfried performs plenty of nude scenes. "I read the script and I was like, 'Wow, this is the riskiest thing that's happening [in Hollywood] right now.' The first thing you think about is that it could have ruined my career. At the same time, I was like, 'This is my chance to show them, to show the industry, to be recognized.'"

Indie films like "Lovelace," says Seyfried, can be less risky thanks to lower box-office expectations. She points her 2011 fantasy flop "Red Riding Hood," as an example of a big-budget film she starred in with big expectations it didn't deliver on. And the failure has clearly haunted her. "'Red Riding Hood?’It kind of f----d me. It didn't kill me, but it definitely wasn't the greatest thing," she admits. "And I loved playing that character —I had a blast! Young girls loved it, but it didn't make the money the studio wanted it to make, so that's on my permanent record now, you know?"
