Justin Timberlake: Not my Penis on Mila Kunis' Phone

Justin Timberlake wants you to know that the penis on Mila Kunis' phone is not his.

The actress became one of the latest victims of phone-hacking on Wednesday, along with Scarlett Johansson, when four risqué pictures were leaked, including one of Justin shirtless in bed and one of him with a pair of pink panties on his head. A third photo showed a man's penis, but not his face. Rumors abounded, of course, that it was Timberlake's, but he denies it.

Timberlake acknowledged the shirtless photo and the photo with the pink panties, but said he had never sent any X-rated photos to Kunis, or to anyone else, for that matter.

Timberlake and Kunis costarred in Friends With Benefits earlier this year, and many people speculated that they were dating, but they insisted they were just friends. Timberlake is now apparently trying to get back together with Jessica Biel.

Johansson, who saw nude photos of herself posted online after her phone was hacked, has enlisted the FBI to find the culprit -- probably the same person or people who hacked Kunis' phone and, earlier this year, Vanessa Hudgens' phone. The FBI confirmed to the gossip Web site TMZ that they were investigating, and rumor has it that they already know the identity of the main hacker.
