Amanda Seyfried on Sex Scenes: 'I'm Not Going to Pretend It's Not Fun' The "Les Miserables" star also dishes on kissing Megan Fox.

March 17, 2014  -- "Mean Girls" star Amanda Seyfried has no problem with sex scenes. In fact, the actress admits she's found love onset before.

"I met my first boyfriend on a soap opera," she told W magazine. "We kissed for the first time on the show. It was like a fairy tale. When you're young, it's hard not to get together with your costar. It's not always the greatest idea, but the experience of making a television show or a movie is so intimate and romantic. And I love acting like I'm in love!"

She continued, "Sex scenes are great. A lot of my costars have been sexy guys my age who are really respectful and cool. So, why not? I'm not going to pretend it's not fun."

Another fond memory for the actress, 28, is kissing Megan Fox in 2009's "Jennifer's Body."

"We kissed really well together," Seyfried told the magazine's reporter at an earlier interview. "We have similar kissing styles! If I watch the scene, it's actually really sexy…We got it done for the masses, and, sadly, the masses didn't show up."

Seyfriend, who is now dating "He's Just Not That Into You" actor, 35, Justin Long, has also dated Dominic Cooper and Ryan Phillippe.

She's more prone to keep her current relationship away from the media than in the past.

"It may be that I'm older, and it may be that social media is everywhere now," she said. "I don't think I was really famous until last year—and I felt like no one paid much attention to what I was doing. That was good. But "Les Mis" was an international hit, and that changed things. Before, I was a little more anonymous."
