The Wiggles fans have been left shocked after noticing Hozier once appeared in one of the children’s band’s music videos.

For those who didn’t grow up singing and dancing to hits like Hot Potato, Fruit Salad and Toot, Toot, Chugga Chugga, Big Red Car, the Australian band was formed back in 1991 and has gone on to become one of the most successful acts in the world.

Now, a new documentary, Hot Potato: The Story of The Wiggles, is charting their road to global superstardom, following the original members Anthony Field, Murray Cook, Greg Page, and Jeff Fatt, as well as those who have taken over the skivvy’s in the years since.

But when taking a trip down memory lane ahead of its release, eagle-eyed fans have come across a totally unexpected cross over.

Back in 2011 the Irish singer-songwriter both starred in a video and provided vocal accompaniment for a song on the band’s Christmas album It’s Always Christmas With You.

Cherry Tree Carol, an early 15th century Christmas carol, was the second track on the album and featured Irish vocal ensemble Anuna, which Hozier was a member of from 2009 to 2012.

In a clip shared on TikTok, a youthful Hozier can be seen, clean shaven and with short hair as he sings alongside members of both bands along a lake.

Unsurprisingly many people’s minds have been blown at this crossover.

‘Is this real?’ one person commented on the clip.

‘I’m crying,’ someone else, clearly shocked by what they were watching, wrote.

‘Delightful. No notes. Thank you, Hozier,’ was another response.

Another person added: ‘I was going to say humble beginnings, but my man performed with THE Wiggles.’

While the music video was released in 2011, but wait was recorded in Ireland around June 2010 when The Wiggles were on their Wiggly Circus tour.

While Hozier doesn’t appear to have ever publicly commented on his time working with the beloved children’s band, he does have an official Wigglepedia which confirms his connection to them.

The unexpected connection comes after Lil Nas X last year did his best to woo The Wiggles, sharing on social media he wanted to team up.

‘Trying really hard to get The Wiggles to coheadline the tour with me. I will keep you guys updated,’ he wrote, also offering them a headline rather than a supporting slot.

While the band responded and said they were ready and willing to ‘wiggle’ with the rapper, they’ve not quite made it on stage together yet.

Metro.co.uk has contacted representatives for Hozier for comment.

Hot Potato: The Story of The Wiggles will be released on October 24 on Amazon Prime.
