Geri Halliwell has written a touching tribute to the cast and crew of the axed Spice Girls stage show in London as she prepares to bid farewell to the U.K. The British singer was in the West End on Tuesday night (21May13) to watch Viva Forever! for the last time before she relocates to Australia, where she has been hired as a TV talent show judge. She took to her blog to thank everyone involved for their hard work ahead of the musical's early closure next month (Jun13), and posted a poignant photo of herself standing onstage in the empty Piccadilly Theatre. She writes, "It's 11pm and I've just come back from the West End theatre show Viva Forever! - to say goodbye... I felt confidant (sic) - almost cocky it was going to be a huge success. Opening night - in my Cinderella prom dress with my fellow Spice Girls, so proud of us having a West End show! It didn't work - 6 months later, it's closing." But the pop star is adamant she has no regrets about Viva Forever!, adding, "It had a bumpy start but the cast and director worked really hard, made great changes, and I can hand on heart tell it's not s**t! - it's good entertainment! I went back again and again. But honestly for many reasons, I don't regret it. "So this is to say thank you to all the people who tried for the Spice Girls, who had the guts to put their heart and soul into Viva. Thanks to all the cast of Viva, the musicians, Judy (Craymer, producer), Jennifer (Saunders, writer), the Spices and to all the fans and theatre-goers who came. It's hard to say goodbye, but sometimes we just have to... So as I leave for Australia for new adventure to be a judge on Australia's Got Talent - I hope it will go well; I'm going to really try my best to find a star and have a blast."
