Actress Jennifer Lawrence may be an outspoken advocate for human rights including LGBT, but when she kissed Natalie Dormer at the premiere of their film "The Hunger Games: Mockingjay -- Part 2" in London, it was clearly an accident.

According to The Huffington Post, Lawrence came up behind Dormer during an interview and was attempting to kiss her on the cheek. But at the same time, Dormer turned her head, and the two ended up locking lips in front of the camera.

It was clearly an accident, and Lawrence comically laughed it off and even apologized to Dormer, who seemed to not care either way. They both had a laugh at the incident, and there was even a reaction from a man behind that seemed priceless at the moment.

"Oh, my God, I'm sorry! We just kissed on camera, and I liked it," Lawrence said.

Dormer had no regrets about the situation either, but as she carried on with the interview, she remarked she needs to get Jennifer Lawrence off her face.

The two are co-starring in the upcoming "Hunger Games" film, which will mark the end of the highly successful franchise that has taken the box-office by storm over the past several years.

The franchise is an adaptation of the Suzanne Collins series of novels. Lawrence stars as Katniss Everdeen, the franchise's main character and heroine. Dormer portrays Cressida, who is aligned with Everdeen in the fight to take down the ominous Capital and win freedom for several districts of blue collar, working-class people long subservient to the Capital, even sacrificing their children to the dreaded Hunger Games meant to entertain the oppressors.

The film will debut in the U.S. on Nov. 20.
