HE has made his name with his hilarious and outrageous alter-ego Keith Lemon – but the man behind the crude jokes and making celebs go red in the face is Leigh Francis.
We take a look at the personalities of the cheeky northerner who hosts ITV shows Celebrity Juice and Through The Keyhole, and try to find out who he really is…
Leigh Francis was born on April 30, 1973, and grew up in Leeds, Yorkshire.
He is an English stand-up comedian, actor, director, producer, writer, and voice artist, best known for creating Channel 4's Bo' Selecta! and portraying Keith Lemon.
He married his wife Jill Carter in 2002 and they have an 8-year-old daughter Matilda.
Leigh was discovered by television presenter Davina McCall, who spotted him when he was doing stand-up comedy.
Davina helped Leigh get his first television role on Dom and Kirk's Nite O' Plenty, where he played Bobby Stark, a man who gives tips on how to win over the ladies.
The series aired on Paramount Television from January to July 1996.
Leigh’s' second television role was playing showbiz photographer Barry Gibson who featured on the early series of Channel 4's Popworld.
Leigh also featured Barry, along with Keith Lemon and Avid Merrion in the series Whatever I Want, which aired late night on ITV in 2000.
Leigh’s major television breakthrough came when Channel 4 offered him a £250,000 deal to produce a series based on his television characters, such as Bobby Stark and Barry Gibson, and in 2002, Bo' Selecta! was born.
The series featured Leigh portraying a series of celebrities by wearing rubber face masks to impersonate them, as well as portraying the main, non-celebrity character, Avid Merrion.
The programme lasted for five series, airing between 2002 and 2006.
Season 4 was called A Bear's Tail, and was based on another of his characters, The Bear.
Season 5 returned to Avid Merrion and was called Bo! in the USA.
Following the axing of Bo' Selecta!, Leigh took one of the series characters, Keith Lemon, and created a brand new show, Keith Lemon's Very Brilliant World Tour, which aired on ITV2 in April 2008.
The show was a success, and subsequently, Leigh created another show featuring Keith, Celebrity Juice, which is massively successful and now in its 17th series.
Since Celebrity Juice started, he only portrays Keith, and has had numerous shows including Keith Lemon's LemonAid, Through the Keyhole and The Keith Lemon Sketch Show.
He even did a movie called Keith Lemon: The Film.
Leigh said in March 2017 that he wants Craig David to appear on Celebrity Juice – so they can publicly put an end to their famous feud.
He appeared on ITV's Lorraine as Keith Lemon, and was interviewed by his friend Fearne Cotton.
And speaking about his dream guests, Keith said: “You're friends with someone I’d love to come on Celebrity Juice, Craig David.
“I’ve asked him a couple of times, I think the last time I saw him was at your wedding and said ‘will you come on?’, and he said ‘I’ve got some music dropping soon’.”
Fearne replied: “I think he will, I think he’s been so busy with his comeback but maybe next year.”
Keith added: “It would be good wouldn’t it? I think it would put a lot of things to rest, publicly and we’ll have just a great time.”
Keith famously did a rubber-masked impression of Craig on his previous show Bo’ Selecta!
Speaking in 2008 to The Telegraph about the negative impact the parody of him had on his career he said: "I was flattered at first and even appeared on his show, but he just went on to become more vicious, knocking down everything I did.
"People would come up to me on the street and say, 'Craiig Daavid' in that northern accent, but I didn't mind – it was like they had a form of Tourette syndrome.
"But it was the only thing I was becoming associated with.
"Even if people liked my records, I felt they might not buy them because I wasn't cool.
"People expected me to be sad, but I'm not at all. It didn't hurt me, but it hurt the brand."
ITV2 has announced a brand new comedy series called Keith Lemon: Coming In America, which will air in 2018 and features six 45 minute episodes involving Keith and his sketch show characters heading to LA to try and break the United States.
The new series will include stars such as Spencer Pratt, Emma Bunton, Sharon and Jack Osborne, Gene Simmons and John Barrowman, with more names to be announced.
