The final instalment in the Twilight series won seven awards at the Razzies, which hands out prizes to Hollywood's worst films.

The Twilight Saga: Breaking Dawn - Part 2 was picked as last year's worst picture at the Academy Awards spoof on the eve of the Oscars.

The finale to the blockbuster supernatural romance dominated the Razzies, including worst actress for Kristen Stewart, supporting actor for Taylor Lautner, director for Bill Condon and worst screen couple for Lautner and child co-star Mackenzie Foy.

Adam Sandler was named worst actor for the raunchy comedy That's My Boy, his second-straight win after 2011's Jack and Jill, which swept all 10 Razzie categories a year ago. Pop singer Rihanna won worst supporting actress for the action flop Battleship.

The five Twilight movies have been well represented in Razzie nominations over the years but had not won any key awards.

"I have a pet theory, which is that the box office on Twilight films is very impressive, but my theory is that instead of 40 million individual girls going to see it, it's eight million girls going to see it five times each. People who love those movies just adore them," said Razzies founder John Wilson.

The Twilight finale also won for worst screen ensemble and worst remake, rip-off or sequel.

For worst picture, it beat Battleship, That's My Boy, the family flick The Oogieloves in the Big Balloon Adventure and Eddie Murphy's comedy flop A Thousand Words.

Kristen's worst-actress prize came for both Twilight and her fairy-tale update Snow White And The Huntsman.

She set a consistent standard of emotional stoniness throughout the Twilight movies, Mr Wilson said.
