The 51-year-old, who is now starring in new political comedy-drama Casino Jack, told USA Today he simply avoids the Hollywood celebrity hotspots.
He says that living as a private citizen, whose personal life is off-limits to the press, 'really doesn't take that much effort'.
'(People) go to the restaurants where the paparazzi are. I don't go to those restaurants. I do something I feel passionate about or something I'm supporting, so I don't show up at every opening.
'I'm an actor and occasionally a director. But first, I'm a human being. If you're consistent, eventually you get boring.'
He added: 'I don't believe there's anything about a person's personal life that's in the public interest, unless they are, you know, abusing funds, doing something that's so remarkably hypocritical that it is in the public interest that it be exposed.'
Spacey has earned himself a best-comedy-actor Golden Globe nomination for playing disgraced lobbyist Jack Abramoff in the new flick.
'For me, it's fantastic,' he said. 'It's a wonderful surprise. I'm very honoured by this because it's really the first central role I've done in about seven years.'
