Mila Kunis and Justin Timberlake are the latest on-screen duo to generate some heat. Their chemistry in “Friends With Benefits,” is unmistakable. Just check out a sexy, new Elle photo shoot.

The couple’s sex scenes are generating most of the buzz about the movie, and early reports suggest they have great on screen chemistry, almost a Robert Pattinson, Kristen Stewart level of chemistry.

When it gets to the inevitable discussion of their very up-close-and-personal sex scenes – the film is rated R – Timberlake is at his most soulful.

“I’m going to tell you I was very comfortable with Mila’s body in this movie,” he said in a recent interview.

“I had no issues with Justin’s body. At all. In the slightest,” Kunis added in the same interview. “I was like, ‘I will deal with this the best that I can.’ ”

“I wanted to be a professional,” he said. “They said, ‘You need to be in bed with Mila.’ And I was like, ‘OK. If that’s what has to be done for this movie, I’ll just suck it up.’ ”

“You did it. You sucked it up,” she replied.

“Seriously, though,” he says, “when the objective is for the characters to be awkward and funny, it does take away some of what’s uncomfortable about being around a full crew of people with no clothing on,” he explained.

“When they call ‘Cut’ and the crew laughs, you’re like, ‘Yes! We’re on to something!’ The two characters can be as vocal as they want because they’re not trying to impress each other.”

Director Will Gluck also provided some tongue-in-cheek analysis about what it’s like to shoot a movie sex scene.

“Lighting Make sure your film stars genetically perfect specimens like Justin Timberlake and Mila Kunis so you don’t have to waste any time lighting,” he wrote in a recent issue of Entertainment Weekly.

There is not one angle in any kind of backlight, top light, sunlight, or klieg light in which this pair does not look stunningly gorgeous. I could have filmed them with a Flip camera and a headlamp, and they would have still looked amazing,” he added.

“If you’re not lucky enough to have Justin and Mila, use candlelight, put the camera as far away as possible, and shoot through a piece of cheesecloth. This new HD format is very unforgiving.”
