Classical musician, model and TV presenter Myleene Klass came up with an unexpected example of crude Irish slang on Channel 4's popular letters and numbers game Countdown.

The edition of the show which will be screened today (April 28) features Klass as a guest on Dictionary Corner and she trumps the show's two contestants with the beloved Irish word "gobsh**e".

She told host Nick Hewer: "I got a rude one. It's an eight . . . gobsh**e."

The show's leader of the lexicon Susie Dent approved the offending word, saying it was "chiefly Irish" and "vulgar slang".

Countdown, which began in 1982, recently picked up a Guinness World Record after it celebrated its 6,000th edition.
