The Duchess of Cambridge is a "real sweetheart", according to Andre Agassi.
The 47-year-old retired tennis legend sat next to the British royal during the 2012 Wimbledon Championships and has fond memories of his meeting with the Duchess.
Andre, who is married to Grand Slam-winning star Steffi Graf, shared: "We sat next to each other and watched the semi-finals about five years ago.
"She’s a sweetheart of a lady. She’s a real sweetheart."
What’s more, Andre said he can empathise with the Duchess, because he also lived his life in full view of the world during the height of his tennis career.
However, the Las Vegas-born icon admitted he didn’t quite understand the enormity of being a royal.
He told HELLO! Online: "I don’t know her well and quite honestly I don’t get the whole royalty thing – in the sense that they’re celebrities on steroids or something.
"I can empathise with some of that, but it’s fascinating to watch from the outside. You have to be on your game all the time!"
The Duchess is a self-confessed tennis lover and recently admitted she dreamed of becoming a professional player after watching Wimbledon matches during her childhood.
She shared: "I have watched Wimbledon, that was very much part of my growing up.
"It inspires young people including myself. Every time Wimbledon is on I am thinking ‘Yes, I could do the same’ and get out the racket."
