(Cover) - EN Showbiz - Robert Pattinson prefers to remain a "mystery" to stop himself becoming an "empty shell".

The British actor has achieved worldwide fame playing vampire Edward Cullen in the hit Twilight franchise. Robert is famously reluctant to live in the public spotlight and rarely talks about his private life. He prefers to remain silent on personal issues to protect his career and loved ones.

"Most actors encourage the attention because they think it will make them have a more lasting career. I don't think that's the case. The more you reveal yourself, the less interesting people find you. Mystery lasts a lot longer, so you just hide," Robert told the December issue of Marie Claire. "If you are just an empty shell with your face stuck on everything, then there's only so long the hysteria can last. It's time to move on."

The 25-year-old hunk often dreams of escaping the pressures of celebrity for a more normal existence.

When asked how he liked to unwind, Robert admits he sometimes turns to alcohol.

"I get drunk," he said before revealing a desire to learn to defend himself. "If I get some time off, I want to get really good at fighting. Then you can just walk down the street and fight back. Or get a gun."

Robert insists he has never been interested in fame.

The star always loved acting, but didn't like being the centre of attention.

"I have never had that feeling where I need to show the world anything," he added. "I remember being at school and I asked someone out on a date when I was 12, and the next day everyone asked if we were going out. I was like, 'Oh God!' I don't think I ever talked to the girl again - it was too much of a hassle." (C) Cover Media
