Kunis, 29, who has been voted the sexiest woman alive, had stripped off in her film "Friends With Benefits", reported Daily Star. "I showed side (bust). I don't need to show (derriere). You get one or the other. You don't get both," she said in a recent magazine interview. The actress, who is dating fellow film star Ashton Kutcher, 35, has also said that she was happy being single. "For four years (before Ashton) I was single. An amazing time. An amazing time. I love being single," she had said.
