Boxing icon, Floyd Mayweather leads the recently published Forbes World's 100 top- earning celebrities 2018. Floyd Mayweather tops the ranking with $285 million in pretax earnings, almost entirely on the strength of his August 2017 fight versus Conor McGregor. "The number one goal is to create stuff for the world", explained the superstar to Forbes in an interview for the package. Oscar winning actor, George Clooney comes second with $239 million, most of it coming from liquor giant Diageo's purchase of Casamigos, the tequila company he co-founded, giving him the best annual take-home of his or any actor's career. Forbes cover star, Kylie Jenner pulled the No.3 spot with $166.5 million boosted by a sprawling cosmetics empire that has her on the verge of becoming the youngest self-made billionaire at age 21, next month. Judy Sheindlin's $147 million puts her No.4 buoyed by the sale of her TV library for $100 million, while Dwayne Johnson places fifth with $124 million rounding up the top five. Other world famous names that made it on the list include; Kim Kardashian-West (No.30, $67 million); The Weekend (No.39, $57 million); Katy Perry (No.19, $83 million); Lionel Messi (No. 8, $80 million); Drake (No. 53, $47 million) and many others. The celebrity 100 list ranks front-of-camera stars around the globe using their pretax earnings from June 1, 2017 through June 1, 2018, before deducting fees for managers, lawyers and agents. Estimates are based on numbers from Nielsen, Pollstar, IMDB, SoundScan, NPD BookScan and ComScore, as well as interviews with industry experts and many of the stars themselves. This year's list members represent 17 countries: the U.S, U.K, Barbados, Portugal, Ireland, Brazil, Argentina, Australia, Switzerland,  Canada, China, Mexico, Colombia, Germany, Spain, Greece and India. Newcomers range in age from Septuagenarian Pink Floyd co-founder, Roger waters (No. 28, $68 million) to thirtysomething pop rock stars Imagine Dragons (No. 89, $36.5 million).
