Sir Mo Farah has reportedly joined the lineup for the upcoming series of I'm A Celebrity... Get Me Out Of Here!

The 37-year-old is a four-time Olympic gold medallist, having triumphed in the 5,000m and 10,000m at both London 2012 and Rio 2016, making him Team GB's most successful ever track athlete.

The long-running ITV reality series, which is renowned for its challenging trials and overall test of endurance, returns for a new series next month at Gwrych Castle in Wales and according to The Sun, Farah will be among those taking part.

"Mo's been a big fan of the show for years and was just waiting for the right time in his career to do it," a source told the newspaper.

"He obviously has an excellent level of fitness and mental focus so will be great at the Bushtucker Trials and will be a positive addition for keeping up team morale for campmates - especially as a lot of the celebs are worried how cold it will be.

"It's his first foray into reality TV so he's a bit nervous about the challenges and will miss his family, but he thinks it'll be an amazing experience and the opportunity of a lifetime.

"It's a massive coup for producers to bag Mo for the series. Everyone's really excited about the signing and think he'll be a hit with viewers."

Farah becomes the ninth celebrity to be effectively confirmed for the show after eight other famous faces - Vernon Kay, Jessica Plummer, AJ Pritchard, Russell Watson, Ruthie Henshall, Hollie Arnold, Beverley Callard and Victoria Derbyshire - were spotted attending a photoshoot for the new series last week.

I'm A Celebrity's new series begins on Sunday, November 15 on ITV.
