The 50-year-old actor claims he's "pathetic" at all things technology-related and stays away from the internet because he worries he might read an upsetting rumour about himself. br br He told Tele 2 Semaines magazine: "I've never googled myself and I never will! I would be too scared to discover lies and horrible things written about me." br br The newly-engaged star, who is set to tie the knot with his 'Rum Diary' co-star Amber Heard, also admits his children Lily-Rose, 14, and Jack, 11, roll their eyes at him whenever he attempts to help them with school projects. br br He joked: "I'm pathetic! You should ask my children! Before, they used to ask my help to do research on the computer - for a class project, for instance. These days, they've realised there's no point. The last time I asked if they wanted help, they told me, 'Go and play your guitar, dad!' " br br The 'Transcendence' hunk is an iPhone convert, however, even though he doesn't remember the name of his favourite application, Instagram. br br Asked about his must-have app, he said: "I've forgotten it's name. It allows you to retouch photos automatically." br br Probed as to whether his favourite subject is Amber, he replied: br br "Among others, but Amber doesn't need any retouching! The photo is perfect every time.
