And the showbiz diva is also clearing out most of the furniture and art from her Renaissance-style Malibu mansion, which she plans to refurbish in a different style. The auction, being run by Sothebys and Juliens Auctions, includes nearly 800 lots and is expected to raise more than £600,000, a portion of which will go to the Cher Charitable Foundation. "I have loved everything I ever bought," she said. "But now its time for them to go on." Wealthy drag queens might like to take note that the sale includes 200 items of clothing and 85 pieces of jewellery from Chers 40-year career. Among the highlights are a Bob Mackie black net gown with multi-coloured embroidered dots and stones worth up to £2,500.

And one of the highest-priced items is a 17th-century oil painting, The Holy Family Served By Angels, by Ercole Procaccini the Younger, which could fetch £25,000. Among the more personal lots is Chers high school yearbook, valued at about £500. Cher isnt the first multi-millionaire star to have a clear-out auction after decades of spending.
