Lohan was in and out of rehabilitation programs last year and acknowledged last month that she had fallen off the wagon at a New Year's Eve party. In November, she served 84 minutes in jail for drunken driving and cocaine possession charges.

Murphy won the worst actor award for playing the hapless hero of "Norbit." He had several parts in the movie and also won worst supporting actor and actress Raspberries for roles as a Chinese man and Norbit's screaming overweight wife.

Murphy had earned an Oscar nomination for his dramatic turn as a troubled soul singer in 2006 musical "Dreamgirls" and some critics said the widespread distaste for "Norbit" -- which hit theaters only weeks before the Oscar ceremony -- cost him support for those prestigious awards.

Like Lohan, Murphy's personal life also made headlines last year when he acknowledged fathering a child out of wedlock with Spice Girls singer Melanie Brown. In January of this year, Murphy and his new wife, Tracey Edmonds, split just two weeks after getting married in French Polynesia.

Few Razzies "winners" show up to the awards, which are open to the public, although actress Halle Berry did make an appearance in 2005 and sent herself up with a tearful acceptance speech when named worst actress for "Catwoman."
