It was a classic Gwyneth Paltrow 'humble brag'.

Dressed up in a trademark Gwynnie word salad, the lifestyle guru revealed that she hasn't smoked a cigarette in seven years - not for health reasons, but because she identifies as one of the new nine 'must have' personality types currently doing the rounds in celebrity circles.

During an interview with British Vogue, the wellness advocate, 53, revealed that she was able to give up smoking on the night of her wedding to Brad Falchuk in 2018, thanks to her 'Enneagram 1' personality type.

'We were redoing our paperwork and I got life insurance, and it said that if anything happened to me and they knew that I had smoked a cigarette, it would nullify the whole thing,' she told her interviewer. 'Because I'm such an Enneagram 1 – which is like, 'integrity is everything' – I never smoked again. I miss it, though.'

The Enneagram scale comprises of nine interconnected personality 'types', each rooted in a person's view of the world and their traits.

Needless to say Paltrow - whose immensely popular wellness and lifestyle brand Goop has amassed her millions, both in cash and loyal devotees - identifies as type one; known as a 'Reformer', perfectionist and all round high-achiever. 

Ones, as they are known, are 'conscientious and ethical', with a strong sense of right and wrong, and characterised by the strive for perfection.

The nine-point diagram is often used by businesses to help explore behaviours in the workplace and the tool is often said to aid self-awareness and the potential road to personal discovery.

It's also increasingly popular in celebrity circles. The creator of the White Lotus, Mike White, had each cast member take the test and then diagnosed each character on the Enneagram - while Tina Fey (a Type 3), says it's 'more accurate than horoscopes'. 

The Enneagram scale was first popularised by the teachings of Oscar Ichazo from the 1950s and Claudio Naranjo in the 1970s - but proponents of the system say it has roots as far back as the ancient Greeks.

According to the Enneagram Institute, everyone emerges from childhood with one 'dominant' personality type, though they may also relate to certain aspects of other types.

Unlike other popular personality tests, such as Myers Briggs, the test looks at internal motivations, rather than external factors.

The Enneagram focuses on whether a person is led by their head or mind (groups 5, 6 and 7), heart and feelings (groups 2, 3, and 4) or body and gut instinct (groups 8, 9 and 1), creating specific overlaps between each section.

There are also 27 different 'subtypes' within each section, providing a detailed and complex personality analysis.  

So, which one are you? Explore below to find out...

As a 'Reformer' therefore, Gwyneth Paltrow credits her self-control to her personality type, revealing that she hasn't smoked in seven years and was last properly drunk on her '43rd birthday'. 

Ones, as they are known, are 'conscientious and ethical', with a strong sense of right and wrong. According to an article in the National Library of Medicine, ones were likely raised in an environment where making 'mistakes were not allowed' . 

In the workplace, this may mean they become teachers or other advocates for change.
