Sir Paul McCartney was spotted leaving an office in London on Thursday after becoming the first ever UK billionaire musician.

The Beatles legend, 81, was sporting a head of long grey locks and a smattering of grey stubble during the outing in the capital city.

The singer cut a casual figure in a blue hooded jacket, which he wore over a blue shirt and trousers, while finishing the look with a pair of lace-up shoes.

Paul covered his eyes with a pair of black aviator shades and left the building carrying a bag of documents in his hand.

The father of five was pictured handing the bag to his driver before getting into the car and heading off elsewhere.

It was revealed Paul had become the first billionaire musician from the UK, according to the 2024 Sunday Times Rich List after his wealth has risen by £50 million to hit the £1 billion figure this year.

Paul claimed the musician top spot in 2023 when he had £950 million, and again in 2022 when his fortune was put at £865 million.

The new milestone follows his successful 2023 Got Back Tour, the increase in the value of his back catalogue and Beyonce covering his band’s song Blackbird on her latest album Cowboy Carter.

As ranked by The Sunday Times Music Rich List, Andrew Lloyd Webber takes second place with £515 million, while Sir Mick Jagger follows with £415 million.

Half a century after they split, the Beatles remain the bestselling musical act in history.

Last year, the two Beatles compilation albums – 1962-1966, The Red Album, and 1967-1970, The Blue Album – were re-released featuring 21 newly added tracks.

A new song by the Liverpool-formed band, Now And Then, was put out in 2023 as the final Beatles track.

It reached number one in the UK charts, and was written and sung by John Lennon in the late 1970s and later developed by the other band members – including George Harrison.

The song was finished by the remaining Beatles Sir Paul and Sir Ringo Starr decades after the original recording thanks to audio restoration technology.

Paul headlined the Pyramid Stage at Glastonbury in 2022 and his 2023 Got Back tour is expected to have grossed $105m (£84.6m) from just 16 shows.

His American wife Nancy Shevell also has considerable wealth in her own right, coming from haulage dynasty.

It comes after Paul proved he’s a full-fledged member of the BeyHive by applauding Beyonce’s version of his song Blackbird.

The iconic musician took to his Instagram to share a heartfelt message praising the cover featured on Beyonce’s new album Cowboy Carter alongside a black-and-white photo of the singers together.

‘I am so happy with [Beyoncé’s] version of my song Blackbird,’ he wrote. ‘I think she does a magnificent version of it and it reinforces the civil rights message that inspired me to write the song in the first place. I think Beyoncé has done a fab version and would urge anyone who has not heard it yet to check it out. You are going to love it!’

McCartney added that he recently spoke with the Texas Hold ‘Em hitmaker about the song over FaceTime.
