Justin and Mila’s Romantic Confessions

In "Friends With Benefits," two platonic pals try to add sex to their friendship without any emotional ties. Sound familiar? The plot is a lot like another movie that came out months ago, but this one stars Justin Timberlake and Mila Kunis, who have demonstrated in interviews leading up to the movie's premiere on July 22 that they have a serious chemistry.

Elle spoke to the stars in a Newlywed Game-style interview that got them to reveal an experience Justin would like to forget, their idea of the perfect first date, and more.

"Friends with benefits": a good idea or a bad idea?

JT: [Smiles] "It is such a good idea -- until it's a bad idea."

MK: "I concur. Ultimately, it ends when someone wants to go and get serious with somebody. More times than not, a person catches feelings and somebody gets hurt."

Playing friends with benefits, what was your co-star most self-conscious about while shooting the nude scenes?

MK [To Justin]: "You've got a fine a**. I was self-conscious about a lot of things. Show me one girl who isn't."

JT: "I'll be honest and say, like, I'm still trying to get into the editing room and cut down on my a** time. I'm like, 'Oh my God, my mom's gonna see that!"

As in the film, have either of your parents ever walked in on you at an awkward time?

JT: "I was caught one time. My mom wasn't cool about it. I was too young to be in bed with a girl, so she was upset."

MK: "I don't think my parents think I've ever had sex."

In this film, there's a five-date rule before you sleep with someone. What if you're so attracted to a person that you want to end the first date in bed?

JT: "Ooh, I would probably steer away from it. As a matter of fact, I definitely would steer away from it."

What's the perfect first date?

JT: "[My perfect first date is] something more simple than extravagant. Scrabble."

MK: "Monopoly."

JT: "Scrabble's a good date. If she can't spell, I don't want to hang out with her. So that's a good test."

MK: "I can't spell at all. Now we'll never be friends."
