Tippi Hedren has no sense of taste or smell

She admitted: "I have no sense of taste or smell anymore, so I don't care about food.

"I had two falls and hit my head in the same place, which affected my olfactory nerves. It was over 10 years ago.

"[I love chocolate] but that's because I loved chocolate before."

And the 86-year-old actress admitted her condition can be "dangerous"

so she's had all the gas-fuelled appliances removed from her home because she'd be unable to realise if there was a leak.

She added: "It's dangerous having no smell though because I cant smell smoke. I've had all the gas appliances taken out of the house."

Though some stars have spoken of their desire not to have their children follow in their footsteps, Tippi is overjoyed both her daughter Melanie Griffith and granddaughter Dakota Johnson have pursued the same career path.

Being interviewed by her famous granddaughter for Britain's Vogue magazine, she said: "I think it's fabulous that you and Melanie are actors. I didn't suggest it to her, she just came home one day and said, 'Mum, I'm going to be in a movie.' "

Dakota added: "I grew up on sets. I thought, this is their job, this is what my job will be."

But the 'Marnie' star didn't always want to be an actress.

She said: "I wanted to be a figure skater - there are 10,000 lakes in Minnesota - but my parents didn't have enough money to send me to classes.

"I used to watch my friends' lessons then go out to one of the little lakes in our neighbourhood and practise and practise."
