Amir Khan and Georgia Toffolo will be the first contestants to face a Bushtucker Trial on I’m A Celebrity… Get Me Out Of Here!

The boxer and the Made In Chelsea star were chosen by the public to tackle the “Critter-cal Rescue” challenge.

The announcement rounded off Sunday night’s launch show, which saw Ant McPartlin return to television screens following his stint in rehab, and Boris Johnson’s father Stanley emerge as an early favourite.

It comes as a tweet resurfaced in which Bolton boxer Amir appeared to dismiss the ITV show as being for 'has beens'. 

In the tweet posted to his account in 2012, Amir was asked if he’d ever appear in I’m A Celebrity, with the boxer replying: ‘No its for has beens.’

People were quick to comment on the 30-year-old's remark...

As well as Khan, Toffolo and Johnson, the line-up of hopefuls this year includes Coronation Street actress Jennie McAlpine and Hollyoaks actor Jamie Lomas, along with comedian Shappi Khorsandi.

They are joined by Saturdays singer Vanessa White and YouTube personality Jack Maynard.

From the sports world, ex-footballer Dennis Wise and Rebekah Vardy, wife of England footballer Jamie, are also taking part.

Sunday night’s show saw some of the stars tackling a terrifying Walk The Plank challenge 334 feet up on the roof of a Gold Coast hotel.

Other tasks included The Wreck, which saw Johnson, 77, rummaging through holes filled with creatures such as crabs and rats to secure tokens.

Things got off to a rocky start for the former MEP as he was bitten by a crab as soon as he started. “I got bitten immediately. Bloody hell!” he declared.

The show went down a storm with viewers, who were particularly taken with Johnson and tickled by his struggle to recognise some of his fellow campers.

Celebrities such as Richard Osman and Vicky Pattison also expressed their thoughts on the episode on social media.

And Nicola Sturgeon appeared to refer to reports that former Scottish Labour leader Kezia Dugdale was set to appear on the programme.

Scotland’s First Minister tweeted: “So it seems I might have briefly tuned into a never-watched-before celebrity TV show tonight under false pretences….”

She added the hashtags “#confused #ImACeleb”.

I’m A Celebrity… Get Me Out Of Here! continues on ITV tonight at 9pm.
