Simone Callahan slams Shane Warne for chapter about Elizabeth Hurley in his new book

Shane Warne's ex-wife Simone Callahan is not happy with him claiming his romance with former fiancé Elizabeth Hurley were "the happiest years of my life."

"I was more in love with [Elizabeth] than I'd ever realised I could be," Warne, 49, wrote in his new autobiography, No Spin. "The more I thought about it, the more I understood that my relationship with Simone was based on a wonderful and close friendship between two newly-married 24 year olds. With Elizabeth it was what I had been searching for."

The former cricketer's shock admission has left Callahan -- the mother of his three children, Brooke, 20, Jackson, 19, and Summer, 16 -- reeling as she recalled the heartbreaking way she found out he was dating Hurley. 

"I only knew Liz Hurley as the funny English actress from the Austin Powers movie until I saw Shane kissing her," Callahan told UK paper The Sun. " I had no idea he was with her in London. I remember getting up in the morning, turning on the computer and seeing those photos."
