Talk about a high and low in a matter of moments. Right after she won the Oscar for Best Actress, Jennifer Lawrence took a tumble on her way up to the stage to claim the coveted statuette. "The Silver Linings Playbook" star tripped going up the stairs as "Les Miserables" star Hugh Jackman jumped to his feet to try to help her.

Lawrence, 22, brushed it off and the audience gave her a standing ovation when she finally reached the podium.

"You guys are just standing up because you feel bad that I fell," she joked in her acceptance speech. "That's really embarrassing."

In the flick, Lawrence plays Tiffany, a widow with a peculiar personality, who forms an unexpected bond with Bradley Cooper's character.

When asked what happened, Lawrence told the Academy backstage: "What do you mean, what happened? Look at my dress. I tried to walk up stairs in this dress. That's what happened. I think I just stepped on the fabric and they waxed the stairs."

Lawrence was wearing a full-skirted Dior Haute Couture strapless gown with a hefty train.

What was going through her mind when she fell? "A bad word that I can't say that starts with 'F,'" she told the Academy backstage.
