Anne Hathaway chose her dress only two hours in advance, the "Les Miserables" actress said Sunday on the red carpet before the Oscars show began.
"I'm 30, and I feel 30 in this," she said. "I know that sounds cheesy."
She also showed off her nails, on which she had her grandmother's initials painted for good luck.
So how did Hathaway feel walking into the ceremony, where she's nominated for supporting actress?
"I'm trying not to think about it too much. I lost my voice in rehearsal yesterday -- that was pretty nerve-racking."
