Rafael Nadal, Novak Djokovic, Carlos Alcaraz and Casper Ruud are all among the tennis stars set to play at a pre-Wimbledon event.
The Giorgio Armani Tennis Classic will now feature Djokovic and Nadal with organisers having confirmed the pair's participation.
The Wimbledon warm-up tournament will be held at the Hurlingham Club in London from 21–26 June.

Reports have suggested that British tennis stars Andy Murray and Emma Raducanu could also potentially be involved, but that has not yet been confirmed.
On Friday, Nadal confirmed that he intends to play at Wimbledon after nursing injuries following his extraordinary 22nd Grand Slam singles title at the French Open.
The 36-year-old has suffered from chronic foot issues in recent years – and the injury flared up again as he won a 14th French Open title. He subsequently travelled to Barcelona after that win to begin radiofrequency treatment, which numbs the nerves on a temporary basis.
Nadal said in a press conference that, after reacting positively to the treatment, he would travel to London, train and take part in some exhibitions before making a final decision.

"My intention is to play Wimbledon, to travel to London on Monday," he said.
"If I travel it is because I intend to play. My plan is to do a week of training and play some exhibitions.
"The joint pain has decreased, but with the treatment, strange things happen and sometimes my foot falls asleep.
“I'm happy – on a day-to-day basis I have less pain. We have to wait and see how everything evolves in the coming weeks."
