In the new romantic comedy "No Strings Attached," Ashton Kutcher and [article id="1656079"]Golden Globe winner Natalie Portman[/article] play two people who try to just be "sex friends" rather than entering into a traditional romantic relationship.

As the "sex friends" moniker might imply, there are quite a few racy scenes in the film and, in particular, one long mash-up of their characters engaging in various acts and positions, in various locations. We'll call it the "sex montage." When MTV News caught up with Kutcher recently, we asked him if there were any bloopers to come out of filming so many challenging-looking scenarios for the montage.

"There weren't really any bloopers," he said. "It's always sort of awkward and giggly, right? Because you're there and you're with someone you sort of know, and there's a lot of people watching," he explained of the awkward factor involved in filming love scenes. "It's always kind of in-between scenes you try to make jokes and divert it, 'Oh it's not a big deal,' try to make it seem like it's not a big deal."

So there were no major injuries suffered then?

"Nah, there were no major injuries," Kutcher assured us. "There was a dirty-feet situation," he revealed. "Because the ground was dirty, and there was one scene where we both had our feet up, and they were showing in camera. We were walking around getting ready to do the scene, and the set floor was a little dirty, so we both had really dirty feet. That was weird, I don't know why. ... No dirty feet in bed," he added.
