Isla Fisher 'heartbroken' over death of author Sophie Kinsella. On Wednesday, the Shopaholic series creator's family announced that she had passed away at the age of 55. Kinsella, real name Madeleine Sophie Wickham, was diagnosed with glioblastoma - an aggressive form of brain cancer - in late 2022. Following the sad news, Isla took to her Instagram Stories to honour the British writer, who penned 2000's The Secret Dreamworld of a Shopaholic and 2001's Shopaholic Abroad, which were adapted into the popular 2009 film, Confessions of a Shopaholic. The Australian actress played Rebecca Bloomwood in the movie, with the feature co-starring the likes of Hugh Dancy, Joan Cusack, and John Goodman. ”Dear Sophie. You conjured Rebecca Bloomwood, a hilarious flawed dream of a comic character - and I was lucky enough to step into her shoes and speak your witty and brilliant words.” ”My daughters grew up being read your books and love them to this day. My heart is broken. You are still my hero, and I'm grateful for you. And though we won't meet again, your light and magic lives on in your incredible characters... I'm so heartbroken that you are gone.” Before adopting her pen name, Kinsella also published novels under her real name Madeleine Wickham, including her 1995 debut The Tennis Party. The author, who went public with her health diagnosis last year, shared four sons and a daughter with her husband Henry Wickham. Other industry figures to honour Kinsella included author Jojo Moyes, who described her friend as "one of the greatest people”.
