US actor Sandra Bullock has been crowned top of the flops at the 30th Razzie Awards, a ceremony which pays homage to the very worst of Hollywood.
Bullock - who could complete an unprecedented double on Sunday if she wins a best actress Oscar for her performance in The Blind Side - delighted guests at Los Angeles's Barnsdall Theatre by appearing to collect her award on Saturday night.
The 45-year-old also handed out DVD copies of her offending performance in the box office flop All About Steve to guests.

"I'll show up again next year if you promise to watch the movie and really consider if it was the worst performance of the year," said Bullock after receiving her "Razzie," a plastic gold spray painted raspberry.
"And if it isn't, I'll give back the Razzie," added Bullock, revealing that she had ducked out of a charity dinner with Hollywood powerbroker and producer Jeffrey Katzenberg to attend the awards.
"Now I've got to get back to that event, because you know, it's Jeffrey Katzenberg and he can basically prevent me from ever working again," Bullock quipped.
