Mila Kunis opted for a butt double in "Friends with Benefits." She told Ryan Seacrest, “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.”
She did get the chance to choose the young lady who would bare all for costar Justin Timberlake.
"These young ladies came in and they were in a casting room, the director and the casting director and my makeup artists and these lovely women had to show us their derrière and we chose the one that resembled my body the most without looking like it is fake,” revealed Mila. [Hollywood Life]
