Prince George adorably sings along with Rod Stewart's rendition of 'Sweet Caroline' during the Platinum Party

Sir Rod Stewart had fans singing along on Saturday night as he belted out 'Sweet Caroline' during the Queen's star-studded Platinum Jubilee concert.

The legendary rocker got the crowd dancing as he sang Neil diamond's much-loved tune with his recognisable raspy vocals.

And it seems Prince George, in particular, was having an absolute blast with the performance.

The eight-year-old royal was spotted in the Royal Box’s front row mouthing the words and joyously waving around a British flag along with his father Prince William.

Before belting out the tune, the 77-year-old singer asked the Jubilee audience to help him perform the crowd-pleasing tune.

"This is a funny one for me to sing," he said, seemingly nervous about the reception it might receive, adding that "the BBC made me sing it."

"Join in, make it comfortable for me!" he asked the crowd.

The Platinum Jubilee was a massive four-day gathering honouring Queen Elizabeth's record-breaking 70-year reign.

The concert took place at Buckingham Palace where a 360-degree stage was set up for the occasion.

In addition to Stewart, other performers included Diana Ross, Elton John, Queen and Adam Lambert, Duran Duran, and more.
