Olivia Wilde isn't worried about getting older.

The 'Drinking Buddies' beauty has admitted she has no qualms about reaching 30-years-old as she thinks it provides her with more opportunities in life.

She told Elle magazine: ''I think at 30 you say, it's my life and I live it for me.

''So now, my thirties seem like this great opportunity to develop the experience and wisdom that will allow me to have an even greater decade in my forties. Thirties feel like a fertile ground.''

Meanwhile, the 30-year-old actress previously admitted she feels ''more fulfilled'' in life as she ages.

She shared: ''I've embraced aging from both identities, as a woman and as an actress. Honestly, wisdom allows you to have a more fulfilled life.''

However, Olivia has insisted she would never go under the knife to keep herself looking good.

She explained: ''I am so saddened and grossed out by young women who look like creepy, old aliens because of their new Barbie noses and lips. Is that a smile or a grimace? Did you melt hot wax on your face, or is that your skin?

''A better approach: Take care of yourself now that you're old enough to know how. Drink water, sleep eight hours (I wish), and don't go within 400 feet of a tanning booth or I'll slap you. Hard.''
