Mila Kunis has revealed that she could not take all her clothes off in “Friends With Benefits” she co-starred with singer-actor, Justin Timberlake.

The Inquistr noted that while the former rival of Natalie Portman in Academy Award winning film, "Swan" has bared some clothes in her latest flick, Kunis has apparently employed a butt-double to ensure she can still keep her bottom to herself.

The young actress who also co-starred with Denzel Washington in "The Book of Eli" had no qualms as she described her butt double in an interview with Ryan Seacrest. The actress was patient enough to walk Seacrest into the selection process of her double.

“These young ladies came in. They were in a casting room and I was there, the director and the casting director and my makeup artist were there. And these lovely women had to show us their derrieres and we chose the one that resembled my body the most without looking like it’s fake,” Kunis was quoted as telling Seacrest by The Inquisitr.

Asked why she opted to get a double for the box-office hit, Kunis explained that she wanted the world to see her body in piecemeal.

“I showed side boob, and I figured I can’t just give everything all away at once… I gotta let it all out in little pieces here and there,” the voice of Meg in “Family Guy” continued.

Meanwhile, Kunis could not have been more thrilled to her upcoming date with a Marine who pulled a stunt asking her out on YouTube, calling it rather “endearing”.
