DWAYNE 'THE ROCK' JOHNSON doesn't take naked photos.

The 43-year-old bachelor has insisted he would have nothing to hide if his mobile phone got hacked because he refuses to take revealing snaps of himself.

He said: ''I don't have anything that needs to be hacked on this phone.''

The 'Fast & Furious' star - who divorced his wife of 11 years, Dany Garcia, with whom he has 13-year-old daughter Simone, in 2008 - instead claimed he's too ''smart'' to take such photos, and is careful about what he keeps on his device following the celebrity hacking scandal in which numerous famous faces had intimate images leaked.

He continued: ''I'm safe! I'm smart! I don't take pictures of myself naked or anything like that.''

But while hacking is the least of his worries, the former wrestler admitted he is always anxious about earthquakes, having recently shot disaster movie 'San Andreas' in which California is struck by a deadly quake.

He told The Independent on Sunday newspaper: ''The scientists we worked with said everything in the script could really happen.

''This sounds like a movie line but it's not a matter of if but a matter of when. We're 100 years overdue.''
