Journalist: Sources Think Oksana’s Sister Leaked Mel Gibson Tapes

Allison Hope Weiner, a senior writer for The Hollywood Reporter, tells ET that her sources suspect Oksana Grigorieva's sister Natalie of having leaked the now-infamous Mel Gibson audio tapes.

"My sources say that they think that it's Oksana's sister Natalie -- that they're very close, that she actually speaks very good English, and that if you took a look at her financial records that you would find out some evidence that she was the one who had sold the audio tapes to Radar," Weiner tells ET.

"There is a seal over the tapes," she continues. "The court has put them under seal; a protective seal. So anybody who leaked those tapes is going to be in held in contempt, who's a party to the proceedings."
