The red carpet moment happened after Lawrence interview-bombed Dormer. The "American Hustle" star was trying to say hello with a kiss on the cheek when Dormer turned towards her at the same time.
"Oh my god," Lawrence exclaimed, before apologising to her co-star.
"We just kissed on camera. And I liked it," she added.
The "Game of Thrones" star continued her interview after the collision, when the reporter informed her that she had some of Lawrence's lipstick on her face.
