Actor Hugh Laurie refuses to leave his house to socialise in Hollywood circles - because he's "paranoid" he will be photographed.
The British star relocated Los Angeles when he began filming House seven years ago, and admits he has become a virtual recluse ever since, leaving his home only to go to work on the hit show.
And Laurie admits he has struggled to give up his privacy for success.
He tells Britain's The Times Magazine, "I'm much more guarded, even paranoid. Pathetic really, but I operate in this horrible world of false names, dark glasses and wide-brimmed hats... I even had the windows of my car tinted because it just became so boring, trying not to get stuck at the front of the line at red lights. Everyone's got digital cameras, and before you know it you've caused a hold-up.
"Truthfully, I pretty much don't go out... Pick up the groceries or collect dry-cleaning? I haven't done that stuff in years. Terrible of me. Terrible. But the last time I did try going to the supermarket, I was photographed and I hated it. I hate people peering at what I've bought, taking photos of what's in my basket. I just hate it...
"You can't go out and lead a normal life. You can't just be yourself."
And Laurie admits he even worries about being watched while he's on set, adding, "In the age of Facebook, Twitter and all the rest, it's hard to confide in anyone. There's this malevolent delight in spreading stuff. I might say something on set and two hours later, I'll read about it on the net. It's happened. The result is that I can't be completely honest in any situation."
