Source of ‘Leaked’ Mel Gibson Tapes Revealed?

(HMG) – There is new theory on how RadarOnline the online sister site to the National Enquirer, got hold of the Mel Gibson rant tapes that have become so infamous.  Several sources close to the case have told The Hollywood Reporter that it was the younger sister of Mel’s ex-girlfriend, Oskana Gregorieva, who shopped around the audio tapes to tabloids before finally selling them to RadarOnline. “I suspect that if the authorities look at the sister, they’ll find a wire transfer or a check to her from the website,” one source tells The Hollywood Reporter.  The sister, Natalie who is allegedly being investigated by authorities, was supposedly turned down by all the tabloids she approached because she wanted them to buy the tapes without first getting a chance to hear them. If  it is the sister and she did go to the tabloids, I wonder why rival media outlets who have reported on the Gibson – Gregorieva scandal, like TMZ have not revealed Natalie is the source if they were really approached by her.  If it turns out that Oksana requested that Natalie sell the tapes on her behalf, she could be found in contempt of court, in addition to the rumored charges of extortion.
