"I didn't really know what it was," Lawrence said of the film, which is based on the Stephanie Meyer novel of the same name.
"When you audition when you're, like, a run-of-the-mill actor auditioning for all sorts of things, you just get, like, five pages and they're like, 'Act, monkey!'" she explained. "When it came out, I was like, 'Hot damn! Wow!'"
Lawrence denied she was jealous of Stewart, who played Bella Swan in the box office smash.
"The one thing that really killed me, like, the only time I've ever been truly devastated by losing an audition ... was Tim Burton's 'Alice in Wonderland.' That one devastated me," the star said of losing the part to Mia Wasikowska.
"She was perfect and amazing," she lauded of Wasikowska. "I couldn't have had a British accent."
Lawrence previously told The Hollywood Reporter she lost the role of Olive Penderghast in the 2010 film "Easy A" to friend and fellow actress Emma Stone.
