Who Did Jennifer Lawrence Kiss on The Set of Her Abscam Movie?

Throughout the past month Jennifer Lawrence has been on the set of David O. Russell's new film, and was recently caught kissing a mystery co-star.

The 22-year-old Academy Award winning actress was caught kissing one of her male costars yesterday while filming a scene in Boston. The scene was in a restaurant where Lawrence and her co-stars were having a conversation before the starlet planted the kiss.

Batman star Christian Bale, who will play Lawrence's husband in the film and Jeremy Renner were also caught on the film's set sporting 70s clothing attire. Renner wore a brown suit and big tie while Bale wore matching brown pants and vest and button-up shirt.

Recently Bradley Cooper was also spotted on set with a permed hairdo while Lawrence fell over and almost went nude in the street.

The untitled film tells the story of a con artist and his partner in crime, who were forced to work with a federal agent to turn the tables on other cons, mobsters, and politicians - namely, the volatile mayor of impoverished Camden, New Jersey.

The film reunites Lawrence, Cooper and Russell after they worked on the Oscar nominee "Silver Linings Playbook" for which she won her Academy Award in February. She will also reunite a third time with Russell for an untitled film set for the Weinstein Company. She was last seen in "The Hunger Games" and "House at the End of the Street." Lawrence will next reprise her role as Katniss in "The Hunger Games: Catching Fire" and in "Serena" also alongside Cooper.

Bale was last seen in "The Dark Knight Rises" and "The Flowers of War." He reunites with Russell after "The Fighter" for which he won an Oscar. Renner last starred in "The Avengers" as Hawkeye and "The Bourne Legacy." He is best known for his work in "The Hurt Locker" and "The Town" for which he was nominated for the Academy Awards.

The film also stars Amy Adams, Elisabeth Rohm, and Alessandro Nivola and will be released on December 27^th.
