Jake Paul has created quite the stir since entering the boxing world.
He even claimed he needed a chiropractor for carrying the sport during 2021. Of course, it prompted responses from some of boxing's finest, including former world champion Tony Bellew.
The retired boxer said he couldn't 'carry a jockstrap of a proper fighter' in a fiery tweet to Paul.
While he may not be Muhammad Ali or Floyd Mayweather like he compared himself to in August, he does rank as one of the most lucrative stars from the last 12 months with earnings totalling up to $40million before taxes.
Paul made an additional $5million from other projects outside of boxing, including endorsement deals with BoohooMan and DraftKings. The social media sensation also comes in at number two on the highest-paid YouTubers of 2021 - returning to the list for the first time since 2018.
His earnings even pushed him past Novak Djokovic ($34.5million) - the world number one in tennis who won three Grand Slam titles in 2021, including Wimbledon.
Paul started 2021 with a boxing record of 2-0 following knockouts of fellow YouTuber AnEsonGib and ex-NBA player Nate Robinson.
He continued his KO run with an opening-round stoppage of former MMA champion Ben Askren before overcoming Tyron Woodley in August.
A proposed bout against rival Tommy Fury fell through just weeks before their scheduled December clash due to Fury having a chest infection and broken rib.
He would once again rematch Woodley - who previously held the welterweight title in the UFC. The first encounter went the distance but the second fight ended in brutal fashion with Paul landing a sensational KO in round six.
The pay-per-view flopped though. Compared to 500,000 PPVs sold in August, the rematch did just 65,000 on Showtime.
He is the biggest earner under the age of 25 but is some way off from topping Conor McGregor who generated around $180million in 2021.
