Paul McCartney is the first U.K. musician to be worth 1 billion pounds ($1.27 billion), according to the annual Sunday Times Rich List published Friday.

The former Beatle ranked 165th overall on the newspaper's annual list of the U.K.'s 350 wealthiest people, coming in ahead of King Charles III himself, who was ranked at 258th with an estimated personal net worth of 610 million pounds ($773 million).

McCartney, 81, saw his wealth grow by an estimated 50 million pounds ($63 million) since last year, according to the Sunday Times, thanks to the rising value of his music catalogue, his 2023 Got Back tour, and Beyoncé's cover of The Beatles' "Blackbird" on her latest album, "Cowboy Carter."

In November, "Now and Then," billed as the "final" Beatles song, was released after surviving Beatles McCartney and Ringo Starr completed a 1977 demo recorded by the late John Lennon. The song topped the music charts in the U.K. and multiple other countries.

McCartney ranked ahead of other famous figures in the U.K., including "Harry Potter" author J.K. Rowling, whose wealth is estimated at 945 million pounds ($1.2 billion), and Elton John, who was estimated to be worth 470 million pounds ($596 million).

The No. 1 spot was claimed by Gopi Hinduja and his family, worth an estimated 37 billion pounds ($47 billion). The family owns Hinduja Group, a banking, entertainment and media conglomerate.
