Mila Kunis and Justin Timberlake are taking time out of their busy schedules to talk to you about a very important cause: the lack of support social media networks have given to people who have 'friends with benefits.'

Or they could just be promoting their latest flick, aptly titled 'Friends With Benefits.'

"Did you know there's no option to choose 'friends with benefits' as your relationship status?" Timberlake asks in the spoof PSA, referring to Facebook.

"Why are we denying a voice to those who are in a casual, sexual relationship with a friend?" Kunis adds.
