Cameron Diaz gives a new theory on her being late. She claims she’s always late because she lives in her own time zone.

The screen beauty - who is romancing pop heartthrob Justin Timberlake - insists she operates a quarter of an hour behind the rest of the world. She said “I exist on another time schedule and it’s 15 minutes later than everybody else. But that’s it, I don’t go over that. I think it’s rude to be on time.”

The blonde actress blames her punctuality problems on being an overdue baby. She said, “I was three weeks late being born. That’s five minutes for every week so it doesn’t matter if I get up two hours early and I’m ready to go an hour before I’m supposed to be there.”
