Taylor Swift has made it on to a list of the world's billionaires, according to Forbes, as her Eras Tour spanning 152 shows and five continents generated more than $1bn (£800m) in revenue.

The 34-year-old superstar, who stole the show at this year's Grammy Awards by winning album of the year for the fourth time, is now said to have accumulated a fortune of $1.1bn (£874m).

According to Forbes, the estimated figure is based on the value of Swift's music, earnings from her world tour and her real estate portfolio.

The US country-turned-pop singer is the only musician to have earned so much money from her songs and performances alone, Forbes adds.

Swift, whose relationship with NFL player Travis Kelce, 34, has gained her - and American football - even more publicity, is one of the 265 people to have joined the 2,781-strong list of billionaires over the past year.

The list has never been longer than this year's, Forbes reports, with the total wealth of those on it amounting to an eye-watering $14.2tn (£11.3tn).

The richest new person on the list is ION tycoon Andrea Pignataro, 53, from Italy, who is now worth $27.5bn (£21.8bn).

Sofia Högberg Schörling and her sister Märta Schörling Andreen, the daughters of Swedish investing tycoon Melker Schörling, are the richest women to join the list with an estimated $5.6bn (£4.45bn) each.

Livia Voigt, 19, is the world's youngest billionaire and the youngest among the newcomers after inheriting $1.1bn (£874m) based on her stakes in Brazilian turbine manufacturer WEG, co-founded by her grandfather.

French fashion designer Christian Louboutin, whose iconic red soled-heels were also worn by Swift in her Eras Tour, also made the Forbes list with an estimated fortune of $1.2bn (£954m).

Swift will be releasing her 11th studio record, The Tortured Poets Department, on 19 April. It will include collaborations with UK-based band Florence + The Machine and US rapper and singer Post Malone.
