Dermot O'Leary 'blows fans' minds' as he reveals his REAL name live on This Morning - and they gasp 'how are we only just learning this?!'

Dermot O'Leary blew fans' minds after he revealed his real name live on This Morning, leaving them asking 'how are we only just learning this?!'.

Opening Tuesday mornings show, Dermot, 51, and co-host Cat Deeley , 48, were introducing themselves to viewers and greeting each other when he dropped the bombshell.

Cat shook Dermot's hand and said: 'Lovely to see you again Dermot O'Leary. Do you have a middle name?'

To which he replied: 'Well my first name is Sean. Sean Dermot O'Leary.'

Looking visibly shocked, Cat asked: 'You're first name is Sean? How did I not know that?'

Dermot went on to explain: 'Normally, If you're born in Ireland or from Irish parents they like to christen you as something and then call you something totally different.

'So I am Sean Dermot but I've only ever been called Dermot. But I am officially Sean Dermot.'

He then went on to tell the story of a time his double name caused some issues in the Irish passport office.

He said: 'Once, I went into the Irish passport office, and pre-Brexit the Irish passport office were quite chilled, so they were like "Oh yeah you're here, we have your passport."

'I looked down and said "Yeah but it says Dermot" and they said "Yeah but you are Dermot" and I said "Yeah but look at the old passport" and they went "Oh, no we just looked at the picture!"

'So now, I am both Dermot and Sean Dermot. Which you can imagine for legal reasons its quite confusing.'

'But quite good when you have a split personality, you can just choose which one you want,' joked Cat.

Dermot gave a sarcastic thumbs up to the camera as he said: 'Yeah, thanks mum and dad!'

Shocked This Morning viewers rushed to social media to comment on the surprise admission from Dermot, who has been on TV screens since 2001.

One wrote: 'I'm sorry?! Dermot O'Learys real name is Sean?! How are we only just learning this!'

Another said: 'Plot twist, Dermot O'Leary is actually named Sean.'

Someone else posted a funny bird meme that said: 'Hello Sean'.

One fan was left so shocked by the news, they failed to hear Dermot's explanation and asked: 'So where did the name Dermot come from?'

However, some were left than impressed, writing: 'Who gives a t*** if he's Sean or Dermot.'

On Friday's episode, Dermot and Alison Hammond has fans in stitches when they took part in their very own Bushtucker Trial live on air .

The hosts shrieked with fear and pulled some interesting faces as they were tasked with retrieving gold stars from boxes filled with toads, snakes, mice and geckos.
