TAYLOR Swift’s megabucks tour has helped make her a US billionaire at the age of just 33.

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.
