Demi Moore has been gracing our screens for more than 20 years. Famed as much for her husbands, divorces and rumoured cosmetic surgery as her acting, Demi is probably one of the noughties biggest comeback queens. Born in 1962 the all-American actress has worked her way up from films such as St Elmo's Fire to the smash hits Ghost, Indecent Proposal and A Few Good Men. In the early '90s she was one of Hollywood's highest paid stars, but a string of flop films such as Striptease, GI Jane and The Juror meant that Moore was on the verge of becoming a Hollywood has-been. Her long-standing marriage to Bruce Willis, with whom she has three daughters, was on the rocks in 1998 and by the turn of the century she was single and twice divorced. But 2003 was Demi's year, she had a rather spectacular beach-body comeback in Charlie's Angels: Full Throttle - which began the surgery rumour mill- and that same year she caught the eye of young hunk Ashton Kutcher, 16 years her junior. Defying claims that it would never last, the couple married in 2005 and are still going strong.

Demi looks great and has definitely made a point of gracing a few red carpets looking rather smug on the arm of one of Tinsletown's hottest hunks. Today Demi and Ashton devote their time to the social networking site Twitter with over two million fans following their daily updates, eager to hear all about the couple's next moves.

Two divorces, three children and a toy boy husband seems to have agreed with Demi, because over the last 25 years she's gone from a daring young thing with bold hairstyles and even no hair, to a glamorous red carpet star. Read on to see Demi's celebrity transformation.
