George Clooney earned whooping $US239 million ($322 million) last financial year, the highest annual earnings in his 35-year career.
His earnings also includes the Casamigos tequila company he co-founded to British spirits company Diageo in June 2017, according to the Forbes Celebrity 100 list.
Forbes said the sale gave Clooney the best annual earnings of his 35-year career in film and television, and put him second on the list behind American boxer Floyd Mayweather.
Forbes said entertainers on its 2018 Celebrity 100 list earned a combined $US6.3 billion ($8.5 billion) before tax, up 22 per cent from last year's list.
"There's never been a more lucrative time to be famous than now, with 11 superstars earning $US100 million ($134 million) or more over the past year," Zack Greenburg, senior entertainment editor at Forbes, said in a statement.
"Entertainers have found all sorts of new ways to monetise their audiences, especially with the help of social media."
