"It is such a good idea - until it's a bad idea!" Timberlake said, smiling when asked how he feels about a no strings attached relationship.  Kunis agreed, adding, "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."

The actors offered up some natural, playful banter when continuing to discuss the subject, with Kunis saying, "I've never met a girl who can have sex without an ounce of feeling," with Timberlake retorting, "Aha!  Is that just a woman convincing herself so she feels like it's okay to have sex with someone?"  To that comment, Kunis responded, "Fifty-fifty," and the former N*Sync singer said, "So it's the same thing as with guys!  Women are just lying to themselves."
