Michelle Pfeiffer feels less pressure to look perfect as she gets older.

The 55-year-old actress, who was crowned the world's most beautiful woman twice in the past, likes to look good but insists she isn't afraid of aging.

The 'Stardust' star told the October issue of Ladies Home Journal magazine: ''Once you get over a certain hump there actually is less pressure. You can begin to look great for your age. You don't have to look young anymore.

''I've moved over to that other side - I'm 55, which is a little too close to 60, but looking great for my age is okay now.''

But Michelle admits she wasn't always comfortable with her looks.

She said: ''Having to watch yourself age on a giant movie screen is simply not natural. It can wreak havoc on your psyche.''

The actress, who has two children, Claudia and John, with her television writer husband David E. Kelley, credits her vegan diet for helping her to stay trim.

She said: ''I haven't always been healthy. When I was in my 20s I smoked two packs of cigarettes a day. I lived on Marlboro Lights and Coca-Cola.''

The blonde beauty is hoping to reignite her Hollywood career with her new film 'The Family' after taking time off to raise her children in San Francisco and despite her huge success, she is still afraid of failure.

She said: ''I still think I'm going to be fired in the first week of every new job I take. Always. In fact, before I even start a movie I'll try to get myself fired or think of a reason I should quit. I guess it's fear of failure.''
