The Hunger Games star hit headlines for the wrong reasons at the SAG ceremony in Los Angeles last Sunday (27Jan13) when her Christian Dior gown fell apart as she went up to collect a Best Actress prize for her turn in Silver Linings Playbook.

Lawrence saw a video clip of the incident for the first time when it was played to her during an appearance on Piers Morgan's U.S. talk show on Thursday night (31Jan13).

She urged the presenter not to play the clip, saying, "Oh, God. Don't do it. Don't play it... Oh my God. Oh my God. I haven't seen this yet. No."

Lawrence then screeched and covered her face with her hands when she saw the moment the bottom tier of the dress fell away and exposed her thighs.

She went on to explain someone accidentally tripped her up when she was walking to the stage, and that may have caused the embarrassing wardrobe malfunction.

The actress adds, "My pants fell off... Somebody trips me on the way. I remember that... I got tripped... (then) it (the dress) starts to fall off. And then I'm keeping it together, keeping it together. And then my pants fall off again... It was a tiered dress."

Lawrence came into the interview late after taping on another talk show overran so she agreed to stay behind after the show ended to record the rest of the chat, which will be aired on Friday (01Feb13).
