The superstar singer, who was seen in New York on Thursday with actors Blake Lively and Ryan Reynolds, has made $400million (£320million) in music sales in the past four years and an estimated $370million (£305million) from tickets and merchandise.

Her bank balance has also received a huge boost from The Eras Tour in the US, for which she sold $700million (£576million) of tickets.

Analysis by Bloomberg finance experts suggests Taylor is now worth at least £890million — the equivalent of $1billion.

Taylor has been seriously savvy with her money since the dollars began rolling in, which has helped her enormous fortune sky-rocket.

She has invested a large amount of cash in an impressive property portfolio, which began in 2009 with a beachfront condo that she still owns today.

Taylor owns several homes in New York, including a mega 10-bed, 10-bathroom penthouse in the city’s uber trendy Tribeca neighbourhood.

She actually snapped up two neighbouring penthouses in 2014 before converting them into a giant one.

Taylor also owns a 1934 Beverly Hills mansion in Los Angeles, which sits in almost two acres of land and was first owned by movie producer Samuel Goldwyn.

The Cruel Summer star’s property has since been granted ‘landmark status’ by Beverly Hills City Council, much to Taylor’s delight.

Elsewhere, the US singer is believed to have splashed her cash on two private jets, including a £40million Gulfstream. There is even an Instagram account dedicated to tracking her planes.

Back on land, she has an impressive car collection too, including a Mercedes-Benz G63 AMG and a Ferrari 458 Italia.

Last year, however, Taylor kept things real by driving around London in a no-frills Nissan Qashqai.

And she is also partial to shelling out on expensive cat breeds.

The animal lover owns three pedigree felines, called Meredith Grey, Olivia Benson and Benjamin Button – and one has a whopping bank balance.

Earlier this year, Olivia Benson – a Scottish Fold – was estimated to be worth $97million due to her huge Instagram following and appearances in her pop star owner’s music videos.

Taylor’s huge wealth is partly credited to her decision to re-record her back catalogue of albums after the rights were sold without her permission.

That decision has earned her hundreds of millions and has helped her top the charts with seven albums since 2019.

Earlier this month, the singer topped the box office in the UK with The Eras Tour Film, which earned more than £76million globally in its opening weekend.

She will bring the tour to the UK next summer when she will perform ten sold-out stadium shows, as well as further dates across the world.

Next Friday she is expected to score her 11th No1 album in the UK with the re-recorded version of her hit album 1989, released yesterday and featuring the singles Shake It Off and Blank Space.

The only female solo artist to have had more No1s is Madonna with 12.

But Madonna, 65, has a smaller fortune and is estimated to be worth £700million.

The young billionaire is currently dating NFL star Travis Kelce
