Behind the scenes with Keith Lemon

Comedian Leigh Francis is one of the only celebs we know who never comes out of character. Seriously, whether it be the red carpet, the bar at the after-party or just a random visit to the heat office, you never get Leigh Francis. It's just Keith Lemon. Still, we're not complaining because Keith Lemon does crack us up. In the above clip we think he almost slips out of character at the end when he starts laughing. Have a watch and tell us what you think.
