"We were filming in Hawaii and there were sacred rocks. You're not supposed to sit on them," she explained on the talk show last week. "I, however, was in a wetsuit... Oh, my god, they were so good for butt-itching."

In her Facebook apology on Friday, Lawrence said she only intended to be "self-deprecating" with her story.
"From Jen, to the internet," she began her apology. "I meant absolutely no disrespect to the Hawaiian people. I really thought that I was being self-deprecating about the fact that I was 'the curse', but I understand the way it was perceived was not funny and I apologize if I offended anyone."
