Mila Kunis has revealed she wasn't tempted to embark on a 'friends with benefits' relationship with Justin Timberlake.
The duo, who star together in new romantic comedy Friends With Benefits, sparked speculation that they were more than just friends when they flirted with each other at the MTV Movie Awards.
But the actress has admitted she wasn't tempted by her co-star.
"Nope, wasn't tempted. If you're friends with someone, let's just leave it at that. There needs to be nothing more."
Mila, whose new film is a raunchy look at whether two friends can enjoy 'no strings sex', insisted the concept isn't as good as it sounds – because things inevitably get complicated.
"I think it's really great in theory but falls short in execution," said the 28-year-old.
"You can't sustain a friends with benefits relationship for a long time. It's inevitable it will either go one way or the other."
But the self-confessed tomboy prefers to keep things simple and sees no problem in being friends with the opposite sex.
"I have plenty of males who are my friends... without the benefits," she continued.
"I don't come from the school of thinking the opposite sex cannot be friends. I make dirty jokes, I'm fine with guys farting, I don't really care, it's not a big deal."
