New research indicates that we should be able to spot cheating spouses at first glance: they look completely different from the average Brit.

The UK’s largest extra-marital dating website Illicit Encounters reveals that the average female cheat is 5ft 3”, aged 37, has a dress size 10-12 with blonde hair and blue eyes: visually very similar to ex-Spice Girl Emma Bunton. The site, which has over 670,000 members and represents 3% of Britain’s married population, carried out an extensive survey with over 5,000 of its female members.

The average woman in the UK however, looks similar to TV presenter Kirstie Allsop. Physically, the average British lady is taller at 5ft 5”, older at 40 years old, is a larger dress size of 14-16 and has black hair with brown eyes*.

Additional research shows that the average British woman earns £22,151 per year, works as a secretary or administrative assistant and drives a Chevrolet Matiz. The average British female cheater however earns much more – £37,000 per year – works in Heathcare, and drives a BMW.

Spokesperson for the site, Rosie Freeman-Jones said:

“I’m not surprised that women on the site tend to be more successful than the average female Brit. These women know what they want and are seizing life by the horns – and it’s these type of women that tend to excel across the board.”

“This data might indeed prove the saying that ‘blondes have more fun’.”

Women have a huge presence on the dating site. Each active male on the site is outnumbered by 3 active females. Additionally the site has seen a 20% increase in women signing up to the site over the last 3 years.
