Sandra Bullock warmed up for the Academy Awards with a stop at the Razzies to collect a dubious honor: a worst-actress prize for her romantic comedy flop “All About Steve.” Bullock swung by the Razzies on the eve of her expected triumph at Sunday's Oscars, where she is considered the favorite to win best actress for “The Blind Side.” If she wins Sunday, Bullock will be the first person to win an Oscar and a Razzie over the same weekend. “I think this is an extraordinary award,” said Bullock, who had promised throughout awards season that if she won the Razzie, she would accept it in person. “Transformers: Revenge of the Fallen” was picked as last year's worst picture and won two other Razzies, worst director for Michael Bay and worst screenplay for Ehren Kruger, Roberto Orci and Alex Kurtzman. Bullock, who also shared the Razzie for worst screen couple with “All About Steve” co-star Bradley Cooper, was the first acting winner to show up at the Razzies since Halle Berry won worst-actress for “Catwoman” five years ago. As she took the stage, Bullock pulled a little red wagon filled with DVDs of “All About Steve,” saying she was giving a copy to everyone in the audience of about 300. The worst-actor Razzie went to siblings Kevin, Joe and Nick Jonas for “Jonas Brothers: The 3D Concert Experience.” The Jonas' pal Miley Cyrus, star of “Hannah Montana: The Movie,” lost the worst-actress category to Bullock. But her dad, Billy Ray Cyrus, was named worst supporting actor for the big-screen “Hannah Montana.” Sienna Miller received the worst supporting-actress Razzie for the action tale “G.I. Joe.” Razzie voters also made worst-of-the-decade picks, with John Travolta's science-fiction debacle “Battlefield Earth” winning worst picture. Paris Hilton was chosen as the decade's worst actress for movies such as “The Hottie and the Nottie” and “Repo: The Genetic Opera.” Eddie Murphy, a 2009 Razzie nominee for “Imagine That,” was named the decade's worst actor for such bombs as “The Adventures of Pluto Nash,” “I Spy” and “Meet Dave.”
