Gwyneth Paltrow smokes one cigarette every Saturday night.
The health conscious star allows herself a single smoke each week, and indulges in her favourite brand from her native America.
She admitted: "My weakness is American Spirit cigarettes. I smoke one every Saturday night."
The 'Iron Man 3' actress used to follow a macrobiotic diet, and although she has eased up on her strict food rules, she insists many people believe how much food she fries at home.
She added to Tatler magazine: "People are always surprised that I have a deep-fat fryer. It's hidden away in the kitchen counter and makes the most incredible French fries."
Gwyneth, 40, also claims she just had a mid-life crisis - although she didn't say what caused it - but claims she overcame it by going on a "mad" trip to a spa.
The Hollywood beauty - who is married to Coldplay singer Chris Martin, with whom she has two children, daughter Apple and son Moses - said: "Midlife crisis? I just had one. So I spent three days at Mii Amo, in Arizona, with psychic massage, hiking and having my colours red. It was mad."
