The Hunger Games star was left red-faced when she accidentally opened the stall door on Claudia Winkleman during a trip to the ladies' room at a British Academy of Film and Television Arts (BAFTA) movie party in London on Friday (08Feb13).
However, Lawrence insists Winkleman was able to laugh off the embarrassing moment, and they are now good pals.
She tells Britain's Mail on Sunday newspaper, ""That woman is so tiny, but she has the strength of an ox. She was leaning against the cubicle door and I had to push so hard to get it open. I didn't realise there was a person behind it - I just thought the door was jammed. What a girl! She's fabulous! We'll keep in touch.""
