Keira Knightley would never leave the house without her underwear.
The 'Pirates of the Caribbean' actress admits being a celebrity isn't easy, but insists fame is not an excuse to be caught going 'commando' in public.
Keira told Empire magazine: "The whole celebrity thing is not magic. They are just real people proving they are sluttier than everybody else because they don't wear any knickers."
The 22-year-old actress continued her thinly veil swipe at young female celebrities like Britney Spears and Lindsay Lohan - who have both been photographed without underwear and have checked into rehab several times this year - by slamming stars who are photographed drunkenly staggering out of nightclubs.
Keira said: "I'm not going to get blind drunk and then stumble out of a club and fall over and vomit in front of people. I'm not saying I don't do that in private, but I try not to."
Meanwhile, Keira appeared at the Venice Film Festival yesterday (29.08.07) looking stunning in an ivory and peach strapless gown.
She is hoping her new movie 'Atonement' - which premiered at the festival - will be as successful as the Oscar-winning British film 'The Queen'.More about Keira Knightley's underwear slam
