Reports have suggested McCready stole the hard drive from former beauty queen Kari Ann Peniche, who also appears naked in the threesome footage, when the pair was roommates on reality TV show Celebrity Rehab.
But McCready is firing back, blaming Peniche for spreading vicious gossip about her.
She tells U.S. news show Access Hollywood, "I did not want to be dragged into all this. I did not want to be a part of this.
McCready denies leaking the tape, which is now at the centre of a police investigation, and she suggests Peniche is the one behind the scandal, adding, "She is evil personified, she is evil in human form. She will hurt anyone she can to make money.
But in an upcoming interview with E! News, which is set to air on Monday (24Aug09), Peniche also denies leaking the footage, insisting she had no knowledge of it until Dane called her last week (beg17Aug09).
She says, "I got a call from Eric, obviously upset... I was like, 'I should go home and check.' If I was going to leak it, I would have done that a long time ago.
Peniche, who was briefly engaged to pop star Aaron Carter, insists she is not part of the police investigation into alleged possible illegal activity: "Nobody raided my house; I haven’t had any contact with LAPD.
The trio involved in the footage and their lawyers have been keen to point out the leaked romp is not a sex tape, but a "naked tape".
The footage shows the naked threesome having fun at home, joking about porn star names. It also features Gayheart and Peniche sharing a bath together as Dane plays cameraman.
