Ronaldo earned $88 million (£61 million) in the last 12 months according to Forbes, making him the highest-paid sports star in the world.
More than a third of that ($32 million/£22 million) was from endorsement deals with companies like Tag Heuer and Nike.
In fact, he rakes in over $13 million (£9 million) from his Nike deal alone.
He also has deals with companies like Herbalife, Castrol, Samsung, and KFC.

If he ever leaves Madrid, the team that buys him will have to pay the club $1 BILLION (£690.5 million) in a buy-out.
So what does he spend his money on? One of Ronaldo's biggest hobbies is cars. He drives a $300,000 (£207,000) Lamborghini Aventador.
He also reportedly owns a Bentley, a Porsche, and a Mercedes, among others.
He's not always careful with them, though. In 2009 he crashed a $320,000 (£221,000) Ferrari in Manchester, where he used to play.

Really, ridiculously nice.
Speaking of property, in 2015 he bought a reportedly dropped $18.5 million (£13 million) on an apartment in Manhattan's Trump Towers.
He's also been spotted wearing a $160,000 Jacob and Co. watch — a perk of having an endorsement deal with the company.

Ronaldo's fame and wealth has made his love life a constant source of media scrutiny. He dated Irina Shayk ...
... a gorgeous Russian swimsuit model and actress.
But after five years together, the couple split up in January 2015.
Ronaldo is also a fashion aficionado.

He has modeled for Armani, and has an underwear line coming out with designer Richard Chai.
But his pretty-boy image may hasn't always been appreciated by opposing fans.
He's not bothered, telling the Guardian "I think that because I am rich, handsome and a great player people are envious of me. I don't have any other explanation."
But he's displayed human moments, like the time he cried after winning the Ballon d'Or last year.

Keep up the good work, Cristiano.
