The actress and model, who is now engaged to the cricketing legend, revealed her knowledge of the sport was limited to the kind of clothes the players wear, reported Hello magazine.
"All I knew was that they wore white. Now, of course, I know a bit more, including the fact they didn't always wear white," Hurley said.
"Elizabeth's knowledge of cricket has come a long way over the last few years. It means a lot to me that she has taken the time to understand the game and I think I've converted to being a fan. But I still need to put some work in about who she's going to support in the Ashes," Warne said.
