THE Chase's Mark Labbett snapped at host Bradley Walsh after he taunted him over his diet.
Mark, 54, who was nicknamed The Beast in light of his size, was not impressed when Bradley, 59, made up a song about biscuits to wind him up.
Cheeky Bradley teased Mark after he moaned he wasn't allowed to eat biscuits - but apparently took it a lyric too far.
Larking around in front of viewers, singer Bradley crooned at the chaser: "Custard creams custard creams jammy dodgers custard creams" as Mark glared at him.
Mark sniped: "[Bradley] takes great delight in showing off what he's allowed."
And as Bradley continued to chant the names of different brands of delicious biscuits, Mark finally snapped: "Sometimes I really hate you".
Mark revealed in October that he'd lost an incredible two-and-a-half stone.
The TV star weighed 378lbs at his heaviest, but detailed in a series of tweets how his body had transformed.
The 54-year-old's lofty 6ft 6ins height and thinner body was plain to see as he posed for pics at a pub quiz
Mark also mentioned former Emmerdale star Lisa Riley - who has lost 11 stone - was his inspiration.
He said: "@Reallisariley I am not at your level yet but in last six months dropped 2.5 stones, four inches off chest and six inches off stomach (sic)".
Mark's weight loss started since he revealed that he is trying to make his marriage work.
He had been trying to save his marriage to wife Katie, 27, following their split in May.
He called time on his relationship with his second cousin after discovering she'd been cheating on him with another man for more than a year, however, they are now giving it another go.
