John Barrowman squealed as Love Island's Kem Cetinay spoiled Game Of Thrones season eight's first episode during his appearance on This Morning on Monday.

The I'm A Celebrity... Get Me Out Of Here star didn't stay up until 2am to stream the HBO series on Sky Atlantic because of his busy schedule on This Morning.

So it's no wonder the actor, 52, screamed when the reality star spilled the details of Sunday's hotly-anticipated episode to him.

'AAAAAAAAH!' He said. In an attempt to salvage the situation, John partially covered his ears while doing the television interview with Kem. 

The Scottish-American's jaw dropped when he was subjected to the spoiler against his will by the Instagram sensation.

ITV bosses beeped out the spoiler during the show to ensure any viewers weren't fuming because they hadn't had the opportunity to see the episode yet. 

John had begged Kem to keep the intimate details of Sunday's episode secret because he hadn't watched it yet.

He responded: 'Do NOT give me anything!' 

Kem morphed into the Westeros heartthrob Jon Snow when he made a dramatic appearance in a mock Iron Throne on This Morning.

He asked: 'Do you think I've pulled [the costume] off? Everyone keeps telling me he's the girls' favourite. I've gone all out but I've left the skinny jeans on.'  

Rochelle was quick to confess she believed she was the only person in the whole world to have never seen a single episode of the Game Of Thrones canon. 

'I've not seen it,' she said. 'I thought I was the only person in the world not to see it.'

Life size cakes of Emilia Clarke and Kit Harington in their respective characters Daenerys Targaryen and Jon were delivered into the TV studios. 

Cheeky John revealed it was a 'dream come true' to take a bite out of Kit's lips from the gigantic cake. 

Nifty Brits looking to escape the spoilers got up at 2am to watch the first episode of Game Of Thrones on Sky Atlantic, the same time it was airing on-screen in America. 

Die hard fans who have been watching the show from the beginning have been waiting two years for season eight.

Game Of Thrones attracted thousands of British people to watch on Sunday and viewers rushed to Twitter to share their thoughts on the epic fantasy series.
