PIERS Morgan refused to apologise for repeating the word "t*t" on Good Morning Britain today as he wished Line of Duty's Vicky McClure a Happy Birthday.
Vicky, who plays Kate Flemming in the cop drama, turns 36 today and the show paid homage to her by airing the the now viral clip of her "best ever line" in the show.
Her character hit back at a smug officer after her gaffer Ted Hastings was arrested on suspicion of being H.
Brandyce tried to rub her nose in it by pulling rank but Kate tells her: "It's Michelle isn't it? Listen Michelle, we're AC-12.
"We do this to other units week in, week out so don't try telling me how it works. We're witnesses not suspects, so stop making a t*t of yourself and p**s off."
The loud mouthed host thought it was hilarious to repeat the word "t*t" on GMB today as bemused Susanna Reid and Kate Garraway stifled their giggles, before he asked: 'What's wrong with saying t*t?'
