Grigorieva sister 'leaked Mel-tirade tapes'

Oksana Grigorieva’s sister is allegedly responsible for leaking the recordings of Mel Gibson attacking her sibling.

A series of audio recordings made by Grigorieva were posted on website RadarOnline.com and it has now been claimed her younger sister Natalie is the person who leaked them.

A source said: “I suspect that if the authorities look at the sister, they'll find a wire transfer or a cheque to her from the website. She and Oksana are very close."

If Natalie is discovered to be the person who leaked the tapes, it could affect Oksana’s custody case with Gibson regarding their eight-month-old daughter Lucia, and could result in the Russian singer's being found in contempt of court.

It has also been claimed Natalie touted the tapes around a number of other of media outlets before agreeing to sell them to RadarOnline.com.

Another source told The Hollywood Reporter: “All the tabloids said no to the deal because they were asked to purchase the audio tapes before hearing them.”

Mel has been the focus of a number of explosive tapes in recent weeks, including one where he apparently admits to hitting Oksana in January while she was holding their daughter Lucia, who was aged just two months.
