Natural beauty: Cameron Diaz went without make-up for a hike with pal Amanda de Cadenet in a Twitter picture Friday

The actress wore a flannel shirt for the outing as she gave a small smile for the camera, while Amanda posed with her head on the star's shoulder.

Cameron wore her platinum blonde hair pulled back, with her long fringe flicked over to one side.
She showed off her naturally clear and smooth complexion, no doubt a by-product of her healthy lifestyle.

Actress turned author: The 41-year-old has been promoting her health tome Body Book, which teaches women how to 'love your amazing body'

Cameron released her health tome Body Book on Tuesday, just in time for the new year.
The blonde bombshell aims to empower other women in making healthy decisions.
The manual is comprised of three parts that cover nutrition, fitness and mind.
In one section, she even encourages women to eschew Brazilian waxes and embrace their natural bikini lines.

What a body!: Cameron watches her diet, but still splurges on french fries, she told People magazine

The actress admitted recently that although she eats healthily, she indulges on occasion.
'I still splurge on french fries,' she told People in a recent interview. 'Discipline is not deprivation.'

Still, the Bad Teacher star has come a long way from her twenties when she was a Drive-Thru queen.
'I used to live on processed fast food,' she admitted. 'I drank a ton of soda and ate greasy, cheesy foods constantly. I'd eat until I hurt myself! I would literally be lying there going, "Why did I do that?"'
She turned her life around when she stopped eating refined sugars and processed foods.
'They are really not meant to be ingested,' the Mask actress said.

Passion for push ups: Though the Knight And Day star has often been spotted post work-out, as she is here in May, she insisted she isn't a gym rat

'If you understand how your body works you can make the right choices,' she added.
'I used to have bad acne and little white bumps. I cut out dairy and my skin changed completely.'
The leggy lady then shared her favorite meal, which is an odd twist on an old breakfast favourite.

Burning calories while on the clock: The California native - pictured here in June on the set of The Other Woman - said, 'acting's a very physical job'

'Savory oatmeal is my favorite thing in the world,' she said.
'I make it al dente, with caramelized leeks, green vegetables and ponzu sauce - so good.'
The Vogue cover girl - who has been spotted numerous times going back and forth to the gym - also admitted she's not working out as much as she'd like to.

Her influence?: Cameron is best friends with health nut Gwyneth Paltrow, who she's pictured with here in 2011

'I'll get back to it,' she said. 'At least when I'm working, I'm being physical all day. Acting's a very physical job.'
Cameron, who has always kept a positive attitude, is characteristically upbeat about heading toward middle age.
'I love getting older,' she told the magazine.
'It's a part of life. If you're not aging, you're dead!'
