London: Oksana Grigorieva has revealed that ex-boyfriend Mel Gibson warned her about his "dark side" at the beginning of their romance, reports DNA.
"At the beginning of our relationship he did say, 'There is a dark side of me I don't want you to ever see... because it will destroy us'," the Daily Express quoted her as saying on CNN news show Larry King Live.
