Actors Sandra Bullock and Bradley Cooper were declared the worst screen couple for All About Steve at the Razzie Awards.
Bullock, who is nominated for the Oscars for her performance in The Blind Side, was also named worst actress for All About Steve at the awards on Saturday in Los Angeles.
She had promised last month that she would claim her prize in person, calling her Oscar and Razzie nominations "exactly the way it should have happened, because it's a great leveller".
"If you don't show up for something like the Razzies then you're a little hypocritical. You can't just show up for the good stuff," people.com quoted her as saying.
Transformers: Revenge of the Fallen was declared the worst picture, while the film's director Michael Bay was named the worst director. It also won an award for worst screenplay.
Worst actor honours were divided among the Jonas Brothers for the Jonas Brothers: The 3-D Concert Experience.
The Razzies is an annual event that began in 1980 to spoof the glitzy Oscars.
