Taylor Swift and her boyfriend Calvin Harris reportedly earned more last year than power-couple Beyoncé and Jay-Z, according to Forbes' Celebrity 100 list.

The pair, whose relationship was revealed only recently, brought in a reported eye-watering $146million (£92m) - in comparison to Beyoncé and Jay-Z’s $110.5m (£70m).

Swift, 25, who demonstrated her star-power earlier this week by forcing Apple into an embarrassing volt-face over their new streaming service, is worth a reported $200 million independently. Her latest album 1989 has also outsold her two previous albums.

Meanwhile, 31-year-old Scottish DJ and producer Calvin Harris – born Adam Richard Wiles – is worth $66m (£42m) , topping rankings of the highest earning DJs in the world since last year.

Both have incredibly lucrative sponsorship deals, helping to boost their musical earnings into the top bracket. Swift has a long-standing deal with Diet Coke, as well as Keds and Sony, while Harris has teamed up Giorgio Armani and Sol Republic headphones.

Forbes’ assessment of the top couples in the music business, this year including only the stars’ annual income, has been teased ahead of their main list, due to be released on Monday.

Only three couples, also including US country stars Miranda Lambert and Blake Shelton, made the final list.
