According Forbes, the richest celeb is this dude, Floyd Mayweather. He made $285 million before taxes last year, due primarily to his August 2017 fight with Conor McGregor.
George Clooney came in 2nd making $239 million. He sold his Casamigos tequila company helping make him the most he's ever made in a year.
Kylie Jenner and her lip kit empire brought her 3rd place with $166.5 million.
Judge Judy made $147 million for 4th
The Rock was 5th making $124 million, doubling last year's income. While his current movie Skyscraper is considered a flop he does still have FOUR more movies coming in 2018 so I think he'll be ok.
