Madonna is highest-earning celebrity

Madonna's MDNA world tour made $305m (£196m) last year. Pop star Madonna was the world's top-earning celebrity over the past year, trumping the likes of Oprah

Winfrey and Steven Spielberg.

The 55-year-old Material Girl made an estimated $125m (£80m) thanks to her MDNA tour, clothing and fragrance lines, according to Forbes.

The magazine said it was the most money Madonna had made in a single year since it began tracking earnings in 1999.

Director Steven Spielberg was at number two with $100m (£64m).

Most of his earnings came from his back catalogue of film hits such as ET and Jurassic Park - which has just been released in 3D to mark its 20th anniversary - as well as last year's Oscar winning Lincoln.

The director also takes a cut of all ticket sales at Universal Studios theme parks.

Lady Gaga featured at number 10 on the list

Third place was a three-way tie between 50 Shades of Grey author EL James, Simon Cowell and shock jock Howard Stern, with earnings of $95m (£61m).

Thriller writer James Patterson follows with $91m (£58.5m), while TV and radio host Glenn Beck earned $90m (£57.8m).

Others in the top 10 included Transformers director Michael Bay ($82m, £52.7m) producer Jerry Bruckheimer ($80m, £51.4m) and pop star Lady Gaga ($80m).

Forbes compiles its annual list of celebrity earnings using input from agents, managers, producers and others to calculate its estimates for each celebrity's entertainment-related earnings.
