Santa Monica/California: Lindsay Lohan was crowned top of the flops at the Razzies here on Saturday, the annual eve-of-Oscars parody that honours the very worst of Hollywood.

The starlet was a joint winner of the worst actress Golden Raspberry (Razzie) for her dual roles in the critically panned box-office dud I Know Who Killed Me, which was also crowned worst picture.

In all the film won eight Razzies, including worst director for Chris Sivertson's effort, worst screenplay for the script based on Jeff Hammon's writing, worst excuse for a horror movie, and worst remake or rip-off.

The honours reward Lohan for her work during a miserable 2007 when her life was dominated by personal woes which included two arrests for drink-driving and drug possession, a brief stint in jail and a stay in rehab for substance abuse.

Veteran funnyman Eddie Murphy meanwhile scored a rare treble of acting Razzies for his trio of performances in the comedy Norbit.

Murphy was named worst actor for his role as the title character and worst supporting actor as well as worst supporting actress.

The un-coveted Razzies, which were created in 1980, are intended as a light-hearted spoof of the Academy Awards, saluting the worst offerings of the movie industry in the previous year.

This year's Razzies were announced at Santa Monica's Magicopolis center, just one day ahead of the Oscars.

Recipients of the Razzies rarely show up to collect their prizes, gold spray-painted plastic gongs in the shape of a raspberry, which organisers say are worth as much as 4.89 dollars.
