Declan Donnelly surprised his co-star Ant McPartlin with a hilarious gift after he suffered a painful fall on stage during the Britain’s Got Talent semi-final on Monday.

Fans were left in shock during the live episode as Ant’s feet slipped right out from under him and he slammed to the floor in a hilarious entrance. 

And though he recovered in time to host the second night’s semi-final the night after, his co-host Dec was on hand to support him after his unfortunate mishap.

Posting a video to their shared Facebook account, Dec surprised Ant with a crafty cup holder – known as a ‘SpillNot’.

The quirky device is made up of a curved plastic arm and nylon carry-strap that is attached to a flat base, creating the perfect balance to stop anything from spilling. 

Revealing his gift to Ant, Dec said: ‘You alright? I got you a little gift after you had a little slip last night.’

Ant replied: ‘Oh here we go, here we go. What is it, is it a bandage? An Elastoplast is it?’

Smiling, Dec continued: ‘No… I was just thinking if you had of been carrying a hot beverage that could have been a catastrophe.’

‘Well yeah, obviously’, Ant acknowledged.

Dec continued: ‘So I’ve got you a little like safety thing like that so you can carry your tea and you’ll never spill a drop.’

Revealing the contraption, Ant was left in shock. 

Smiling, he gasped: ‘No way! What! Oh my god. 

‘Even I can’t make a mess of this. Yes!’

But as Ant got increasingly excited by his new gift, he started testing the contraption by swinging it in circles around him. 

Watching on, Dec said: ‘Woops, be careful…’

But as he continued, it appeared as though the device, which works using physics and a centripetal force, was not foolproof.

Swinging the device around, Ant then dropped the mug which contained a cup of hot tea, spilling everywhere and smashing around him.

Disappointed that his gift wasn’t entirely successful, Dec said: ‘I’ve still got the receipt, I’ll take it back.’

The morning after Ant’s fall, his co-host Dec admitted he ‘nearly wet himself’ with laughter after Ant slipped as he walked on stage following a performance by former BGT winners Diversity. 

On Tuesday morning, Dec uploaded a video to the pair’s joint Instagram account where he couldn’t resist poking fun at his co-host.     

Speaking to the camera, he said: ‘Well, did you see that fall? I nearly wet myself and farted at the same time. Lets see how he is. How are you Ant?’

He then walked into the next room where Ant was sat, with the star replying: ‘I can hear you, shut up! Shut up! I’m resting. I’m resting my back.’

‘How are you?’ Dec asked.

‘What do you mean, how am I? It’s a bit sore like,’ Ant said.

‘I’m not surprised,’ Dec said, laughing.

Ant replied: ‘It was all right, I think the adrenaline gets you through it and now it’s a bit like “ooh, I think I need a bit of ice on that.’   

Dec asked: ‘You’re OK? You’re gonna be here tomorrow? 

Reassuring fans he was fine and would be back for the next semi-final, Ant said: ‘I’ll be here tomorrow.’

Dec replied: ‘Oh thank God for that, I’m not doing it on my own.’

Meanwhile, the Britain’s Got Talent twitter account also confirmed Ant was OK, tweeting: ‘Don’t worry, Ant’s fine!’ 

The first live semi-final kicked off with Ant and Dec introducing the four judges, Simon Cowell, Amanda Holden, Alesha Dixon and Bruno Tonioli.

They then surprised the audience with their special guests, 2009 BGT winners Diversity who performed on stage.

At the end dance troupe leader Ashley Banjo ran forward as Ant and Dec came running to join him.

But Ant’s feet slipped and he slammed to the floor in a hilarious entrance. 

The judges fell apart laughing as Ant got back on his feet and Dec asked him if he was okay.

He replied: ‘I wet myself and farted at the same time!’

Laughing off the blunder, the hosts made their way to the judging panel to talk before the show.

Amanda wasted no time in asking Ant: ‘Is your coccyx alright?’

He assured her he was fine and Simon quipped that it was the comedy duo’s best entrance yet. 

Dec took the opportunity after the break to replay the fall in slow-motion much to Ant’s displeasure.

Ant quipped: ‘I’m making a claim! That was a very slippy stage.’

Dec added: ‘You better lawyer up.’

Viewers at home couldn’t help but react to the hilarious moment and took to Twitter to voice their amusement.

One joked: ‘Ant just hit the Dec’.

Another asked: ‘Hope you’re okay Ant?’

A third praised: ‘Poor Ant! He’s handled it so well through the pain and embarrassment of everyone milking it’.

A fourth added: ‘People falling on live TV will always be funny idc’.

And a fifth agreed writing: ‘Ant just absolutely Dec’d it live on TV’.
