She was a guest at one of the glitziest events in the celeb calendar with a no doubt lavish meal on offer.

But Faye Dunaway, 75, took matters into her own hands at the recent amfAR gala in Cannes according to a new report in Page Six.

The Bonnie and Clyde star bought along a pair of scales to weigh out her food and calculate her calories at the A-list event held at the famed Hôtel du Cap-Eden-Roc.

Strict: Faye Dunaway bought along a pair of scales to weigh out her food and calculate her calories at the amfAR gala in Cannes last week according to insiders

The notoriously fiery actress bought along the scales in a paper bag according to the Page Six source, who told the publication: 'She sat at her dinner table and pulled out the scale from a paper bag.'

The insider adds that Faye 'asked for a very bland meal which she then proceeded to weigh. She weighed all of her food, including her salad and fish, before eating. We've seen a lot of stars make strange requests, but this was a sight.'

A representative for Faye told the MailOnline when asked about the incident: 'Ms. Dunaway has always taken care of her diet and general wellbeing, what may be considered slightly eccentric is part of her charm'.

The portable scales seem to be a favourite of Faye's with friend to the stars Michael Winner revealing in his 2010 book 'Unbelievable! My Life In Restaurants And Other Places', that the scales were whipped out of her bag at every meal he had with the Hollywood star.

'Faye was always immensely careful about what she ate and still is. Hence, she has never put on weight,' Michael explained.

'Whenever you had lunch or dinner with her, she'd take some small round scales out from her bag and place them under her plate. Then she'd scoop food off the plate until the scales registered a certain weight.'

'I asked her once: "Are you still using the scales, Faye?" She said: "Yes, people laugh at me but I don't care. They keep me slender."

'I think it's a brilliant idea because, as I've always said, you can lose weight simply by eating less. It doesn't ­matter what you eat. Just eat less.'

Faye herself has admitted to having some quirks, telling Esquire in a rare interview last year 'I'm a bit high maintenance, but it gets your attention. A little hot and cold never hurts,' adding that 'It doesn't really matter what other people think.'

She shot to fame in 1967 playing Bonnie Parker opposite Warren Beatty in Bonnie and Clyde, for which she was nominated for her first Oscar.

The trained actress then went on to impress in the 1974 suspense film Chinatown and bagged an Academy Award for Best Actress for her role as Diana Christensen in the 1976 film Network.

Her award-streak also resulted in a Golden Globe Award win for Best Supporting Actress in the 1984 TV miniseries Ellis Island.

After a six-year acting hiatus, Faye will return to the big screen this year in the horror The Bye Bye Man, alongside Douglas Smith and Cressida Bonas.

She was also the guest of honour at the Lumiere Film Festival back in 2014 where she received a standing ovation for her work in the acting business.

Faye is also a mother to Liam O'Neill, 34, with her photographer ex-husband Terry O'Neill, who she divorced in 1987.
