Mila Kunis And Justin Timberlake Get Naked In 'Friends With Benefits' Red-Band Trailer

The red-band trailer for the new Justin Timberlake-Mila Kunis romantic comedy "Friends With Benefits" requires no introduction -- the title basically explains the premise -- but we're going to provide one anyway, just for yuks. JT and Mila play two pals who realize that they're completely wrong for each other romantically (which, in movie terms, means that they're completely right for each other), but they still want to make the beast with two backs together. And so they agree to become -- you guessed it -- friends with benefits.

Of course, they soon discover that there's no such thing as "no strings attached"... which reminds us of this Natalie Portman-Ashton Kutcher rom-com that recently got a trailer and is also about best pals who decide they can do the nasty while keeping things platonic... but soon discover they may have been mistaken. So what was that flick called again? Oh yeah, "No Strings Attached."

Anywho, the trailer for "Friends With Benefits" sells itself: It's basically two-and-a-half minutes of Timberlake singing that Semisonic song "Closing Time" and having sex with Kunis, usually both at the same time and often while the two of them are naked.

And, if you want to check out the "No Strings Attached" trailer for comparison's sake, your wish is our command (by which we mean it's below). "No Strings Attached" hits theaters January 22, and "Friends With Benefits" joins the canon of "friends who decide to have platonic sex and discover they're in love" movies on July 22. Which will perform better? Your guess is as good as ours.
