Keith Lemon is the eccentric character created by comedian and actor Leigh Francis.
It's easy to confuse Leigh's persona with what he's like in real life, as the 48-year-old rarely makes public appearances out of the role.
The playful alter ego is the face of ITV gameshow Celebrity Juice and Through The Keyhole, the show in which guests guess whose house Keith is exploring.
Now, the character of Keith Lemon is the host of E4's latest reality show, The Real Dirty Dancing.

But as Leigh returns to screens, viewers are probably wondering how his stardom came about, and who the presenter really is behind closed doors.
Leigh, born in Leeds, was brought up on a council estate before his father passed away from cancer aged 47, MyLondon reports.
He went on to gain a qualification in graphic design at school and broke into showbiz after working in stand-up, with his character Keith reportedly loosely based on a friend.
Viewers were first introduced to Keith Lemon in 2000 on a show called Whatever I Want, alongside his other comedic characters Avid Merrion and The Bear.
While Leigh keeps his personal life relatively private, he has been with wife Jill Carter, a beauty therapist, for three decades.
The pair first met in 1991 when she was 16 and he was 19.
They married in 2002 in a castle in North Yorkshire, and have two children, Matilda and Dolly.
To mark their wedding anniversary back in 2017, he tweeted: "What a lovely anniversary evening. Together 25 years! Married 14 years! Love you Mrs F ever since we were kids xxxxxxxxxx."
The Real Dirty Dancing airs Mondays and Tuesdays at 9pm on E4.
