He has performed in front of The Queen, President Barack Obama and dozens of world leaders.
But Maltese tenor Joseph Calleja looked absolutely thrilled on Sunday as he rubbed shoulders with some of the greatest tennis players in the world.
The opera star was at The All England Lawn Tennis Club in Wimbledon to perform at at a star-studded ceremony to unveil the new roof over number one court.
The Maltese singer raised the roof with his performance before posing for pictures with former world champions John McEnroe and Martina Navratilova.
He wrote on Instagram: ‘What an immense pleasure to meet the GREAT Martina!’
Other players taking part in the opening ceremony included Venus Williams, Pat Cash, Jamie Murray, Goran Ivanisevic and Kim Clijsters.
The £70million retractable roof, which took three years to complete, is part of a £200 million redevelopment of Wimbledon, according to The Times.
The new roof is identical to the one used on the 15,000-capacity Centre Court and is a boost for Wimbledon as they look to reduce the number of match delays due to rain.
After being closed, it takes around 20 minutes for the air conditioning to adjust to a suitable playing atmosphere.
Along with the new roof, and new seats, existing seats have been replaced with wider, more comfortable ones.
