Sparks hit the Glastonbury Festival stage in Worthy Farm final night time and kicked off their setlist with an unbelievable shock.

Singer Russell Mael instructed his viewers: "Hopefully as many of you know we have a brand new album, it just came out a couple of weeks ago. We have a super special treat tonight.

"We did a video for this tune not too long ago and we had the good honour of getting the good actor Cate Blanchett be part of us – the place are you Cate Blanchett?"

The Australian actress hit the stage in the same yellow suit, green sunglasses and red headphones she donned in the band's music video for The Girl Is Crying In Her Latte.

She then danced and performed throughout the song, but the surprises didn't stop there.

Eagle-eyed viewers pointed out that at the end of the performance, Cate huddled up with Sparks to get a photo taken.

But the person behind the lens was none other than Hollywood director Edgar Wright.

The British filmmaker is best known for Shaun of the Dead, Hot Fuzz, Scott Pilgrim Vs The World, and Baby Driver.

In fact, Wright and Blanchett have a strong connection behind the camera.

The Oscar-winner apparently adored Shaun of the Dead and got in touch with Wright to tell him as much.

After that, Blanchett had an uncredited cameo in the star's follow-up movie, Hot Fuzz. Many fans didn't even realise it was the Lord of the Rings star at the time, as she was playing a forensic scientist who was wearing overalls and a mask.

At the time, Wright laughed: "Let’s get an Oscar winner in there however not see her face."

Sparks previously spoke about meeting the actress for the first time as well. The band said: "We met Cate Blanchett in Paris on the Cesar Awards final yr.

"Little knowing that a year later one of the great actors of our time – and a splendid person – would graciously consent to lending her booty-shaking skills to the first video from our new album."
