Cruz Beckham's Instagram followers go crazy for video of him playing guitar at Spice Girls reunion

Cruz Beckham has delighted Spice Girls fans by sharing a previously unseen clip of him strumming along on a guitar as his mum Victoria and her former bandmates sing along to their hit Mama.

The impromptu performance came as the Viva Forever hit-makers came together for a rare reunion to celebrate Victoria’s 50th birthday party last month.

It marked the first time that they had performed together as a five-piece since the closing ceremony of the London Olympics in 2012.

Cruz clearly knew he was on to social media gold as he captioned his post: “You’re welcome...”

The move sent his 2.1m followers into utter meltdown.

“Cruz just broke the internet,” wrote one person in the comments section.

“Thank you so, so much,” penned another. “You are not even close to understanding how much this tiny clip brings to us fans…Thank you Cruz,” they added.

While a third declared: “We need a Reunion Concert!”

This sentiment was then shared by several people online who were calling for a full-blown concert.

Victoria recently dashed that hope however in a new interview with Oscar-winning actress-turned-wellness guru Gwyneth Paltrow.

She told the Goop founder:: "So often people say 'Are you going to go back on tour?' I am not going to go back on tour, on the record. But I loved that time, and I'm so thankful, I love the girls and I'm so appreciative of the fans."

Speaking about reuniting with her fellow spices at her lavish milestone birthday bash, she said: “ "Not gonna lie, had a bit of alcohol, seemed like a good idea and I did have a lot of fun."
