Novak Djokovic and Rafael Nadal are among the star names set to take part in the Six Kings Slam next month.
Young star Carlos Alcaraz will also play in the Six Kings Slam, which will take place in Saudi Arabia in mid-October.
Djokovic, Nadal and Alcaraz will be joined at the event by Jannik Sinner, Daniil Medvedev and Holger Rune.
The Six Kings Slam champion will win $6million (£4.8million), with each player receiving $1.5million just for taking part.
Incidentally, world number one Sinner earned £1.5million for his Australian Open win at the start of the year.

Andy Murray reacts to Liam Broady as Six Kings Slam video emerges
The event is certain to draw plenty of attention, with British tennis player Liam Broady certainly excited to tune in after a new promotional video emerged.
Sharing the footage on X, he wrote: “Speechless as to how damn cool this promo is. Probably best I’ve ever seen in tennis. Would watch this movie. 10/10.”
But that certainly didn’t impress his compatriot Andy Murray, who replied: “Except it’s not a movie and you won’t watch it because it’s an exhibition tennis event that nobody cares about.”
Novak Djokovic and Rafael Nadal reunion on the cards in Saudi Arabia
Former world number one Murray, who retired from tennis earlier this year, clearly won’t be watching the event in Saudi Arabia.
It will kick off with Sinner facing Medvedev, before Alcaraz meets Rune, with Djokovic and Nadal sitting the early round out.
The Serbian will then take on the winner of the first match, with Nadal set to meet the winner of the second.
It sets up a potential final clash between legendary figures Djokovic and Nadal, although the likes of Sinner and Alcaraz will likely have something to say about that.
With no ATP rankings points on the line, it does seem that the exhibition tournament is solely serving as a huge payday for six of the game’s top players.
