The comedian first found fame under the name Lee McKillop after winning a major competition at the Edinburgh Fringe in 1995.
Viewers of The 1% Club were left surprised when host Lee Mack casually revealed the real surname behind his famous stage name.
The comedian, who has become one of British television’s most recognisable comedy faces, was chatting to a contestant when he discovered they shared the same surname.
The contestant introduced themselves as McKillop, prompting Lee to reveal that it is his own family name too.
The revelation caught the audience off guard, particularly because most viewers know him simply as Lee Mack.
Born in Southport, the comedian has gone on to become a familiar face on primetime television, most notably as the host of ITV’s The 1% Club.
The show takes a very different approach to traditional quiz programmes. Rather than testing contestants on general knowledge, it challenges them with puzzles designed to test reasoning, logic and common sense.
A starting group of 100 contestants is gradually reduced as the questions become increasingly difficult, with the ultimate goal of reaching the notoriously challenging 1% question and competing for a share of the jackpot.
Lee Mack’s real name is Lee McKillop
While speaking with the contestant on a recent episode, Lee revealed that McKillop is his real surname.
The name dates back to the beginning of his comedy career.
In 1995, he won the So You Think You’re Funny competition at the Edinburgh Fringe Festival, performing under the name Lee McKillop.
Long before becoming a household name through television, however, Lee had a very different working life.
After leaving college and failing his O-Levels, he reportedly found work cleaning the stables of legendary racehorse Red Rum, the three-time Grand National winner.
According to Wales Online, Lee landed the job despite never having ridden a horse before.
His early experience around racing later appeared to influence his comedy. One of his early television sketches, on The Sketch Show, featured a quick-witted racing jockey.
From comedy newcomer to TV favourite
Lee eventually became best known for creating and starring in the BBC One sitcom Not Going Out, which helped establish him as a major figure in British comedy.
He also became a regular panelist on Would I Lie to You?, appearing alongside David Mitchell and Rob Brydon.
These days, he is the face of The 1% Club, where his interactions with contestants have become an important part of the show’s appeal.
After players give their answers, Lee frequently chats with them and turns their names, jobs or appearances into the subject of playful jokes.
The programme itself has built a reputation for questions that can look deceptively simple while requiring careful observation and logical thinking.
Some of The 1% Club’s toughest questions
Over the course of the series, contestants have faced a wide range of brainteasers.
Some have involved comparing butterfly images to determine which were identical on both sides, while others have asked players to identify symbols that remain in the same order when read in reverse.
Contestants have also been challenged to calculate the number of possible combinations of four digits displayed on one hand.
Another puzzle involved decoding a secret message from an old diary, while a separate question asked players to count the number of eyes hidden among letters, symbols and emojis.
One particularly difficult 1% question involved a grid numbered from 1 to 49. Players had to follow a sequence beginning at the central square and work out where the word “SEWN” would take them next.
And not every question is quite so intimidating. One puzzle simply asked contestants to identify a common food whose letters had been rearranged into alphabetical order: ABDER.
Lee Mack’s family life
Away from television, Lee married his university sweetheart, Tara McKillop, in 2005 in a private ceremony.
The couple had welcomed their first child, Arlo, the previous year and later expanded their family with two more children, Louise and Millie.
For viewers who have known him as Lee Mack for decades, however, his appearance on The 1% Club offered an unexpected reminder that the comedian’s real surname is McKillop.
And while the revelation may have surprised some viewers, it has been part of Lee’s story since the very beginning of his comedy career.
The 1% Club continues on ITV1 and is available to stream on ITVX.
