The Hunger Games star was left shocked after learning some male actors sometimes use their tongue during passionate smooches to see what reaction they get.
Despite telling Britain’s Glamour magazine that she “doesn’t mind the tongues. It should be all real”, Lawrence is now concerned she may have fallen for the trick.
The 21-year-old actress, who is dating actor Nicholas Hoult, jokes, “God, am I wrong? There I am thinking, ‘This is just the way it is’, and maybe all these men have been taking advantage of me.”
However, one male co-star she is sure would not pull the stunt is Bradley Cooper, who stars alongside her in the forthcoming The Silver Linings Playbook.
She adds, “He’s respectful, not gross – not one of those Hollywood guys who is like, ‘Oh, I can sleep with anybody I want.’ That helps. It means that when it comes to the romantic stuff, you don’t freak out.”
