"Friends with Benefits" co-stars Justin Timberlake and Mila Kunis might share a steamy relationship on-screen, but that's pretty much where the sexy ends. So when TMZ reported a rumor that nude photos of the two actors were found in Kunis' cellphone, they laughed it off and set the record straight.

"We would like to confirm that the photo addressed in the media of Ms. Kunis was in fact not from any phone but from an inactive email account that has not existed in three years," reps for both stars tell People. "In regards to the other photos in question, they were never exchanged between the two parties."

One photo features Kunis in a bathtub while the other two are allegedly of Timberlake lying on a bed.

Not able to resist making a joke about the incident, the message had a final comment about the rumor. "In closing, Mr. Timberlake would like us to make it clear that while he might write songs about putting things in boxes, he never has and definitely doesn't make a habit of taking any photos of them and sending them." The message refers to Timberlake's "Saturday Night Live" musical sketch, "D--k in a Box."

Both actors are currently working with authorities to investigate who hacked into Kunis' phone.
