Billionaire tennis star shows support for Donald Trump at Novak Djokovic's match

Ion Tiriac was back in attendance at the on Tuesday to show his support for . The three-time Roland Garros champion sailed into the second round following a 6-3, 6-3, 6-3 win over Mackenzie McDonald and will now face a tough test against home favourite Corentin Moutet.

But Djokovic wasn't the only famous figure Tiriac was backing from the stands at Court Philippe-Chatrier. That's after the Romanian billionaire continued to flash his 'Make America Great Again' cap for all to see. The slogan was coined by and has become synonymous with , the President of the United States who popularised the term in his first election campaign. And while the 'MAGA' phrase has become divisive since 2016, Tiriac clearly isn't worried about any backlash he may receive for his loyalties.

The 86-year-old is often spotted taking in the action at Roland Garros, where he and Ilie Nastase combined to win the men's doubles crown in 1970. Tiriac, who is estimated to be worth £1.6billion by Forbes, was also a quarter-finalist in the 1968 singles tournament but never quite reached the same heights at any other Grand Slam.

Except his MAGA hat is somewhat unique, and not just becase of its alternative colour variant. The caps have achieved cult status and usually come in red with white text, like Trump himself often sports at rallies and other speaking events.

icon Tiriac's version looks almost evangelical in all white with gold writing on its front. But it also boasts a distinct autograph scrawled across the peak, which is understood to belong to none other than Trump himself.

The headpiece has been perched atop Tiriac's crown for most of this week as he's taken in the entertainment in Paris. And while Trump's second term as President has ushered in new waves of controversy, his fellow billionaire appears unwavering in his faith.

The US stock market crashed earlier this year when Trump on countries across the globe. Romania is a part of the European Union, upon which the 45th (and 47th) President of the United States imposed a 20% hike on all imports - though many of those increases have since been rolled back.

There's a good chance business tycoon Tiriac may well have seen some of his business practices affected by such a spike. And yet it doesn't seem to have damaged his appreciation of the US leader one bit.

Tiriac once developed and owned the Madrid Open, as well as playing a key role in promoting the Italian Open as a Masters 1000 event. He was elected to the International Tennis Hall of Fame in 2013 and is one of the richest figures in the sport.
