Though there's plenty of smooching in David O. Russell's new film "American Hustle," there's only one kiss that the two female stars -- Jennifer Lawrence and Amy Adams -- are consistently asked about. In the film, the A-listers lock lips after having a contentious relationship.

"She does a great job at it! She has very soft lips," Adams, 39, told "Extra" of Lawrence, 23. "She's a really awesome woman. Everyone's chemistry is so electric in this. The volatile energy between Jennifer and I, it almost borders on intimacy because it's so immediate and so there and then she kisses me."

Adams' kissing partner won the 2012 Oscar for her role in the last David O. Russell film, "Silver Linings Playbook." She also quickly won over hearts after tripping up the stairs on her way to accept the award.

Lawrence gushed, "Getting to fight with Amy was just the funniest. We'd be cracking up, they'd call cut and we'd just start laughing. These kind of women are just so fun to play, and then we kissed. It was great!"

But there's one particular kiss she enjoys getting the bragging rights to.
