Cage, 50, who stars in the new movie 'Joe', recently had dinner with co-star Tye Sheridan and director David Gordon Green when he was spotted using his friend's cellphone, reported New York Post.
Diners overheard Cage say he was checking to see if his own phone could be erased in case it fell into the wrong hands.
"He told his group about the phone and they asked him what he was worried about. He said, 'There is one text message that I would hate if it got out there'," a source said.
