Talk about a real burn. It looks like Heidi Bivens' mother won't be sending her daughter's ex-boyfriend Christmas cards anytime soon as she's gone on the record to not only slam the actor, but his new wife Jennifer Aniston as well. Justin was in a relationship with Heidi for over 14 years before he evidentially dumped her to start a relationship with Jennifer, who he went on to marry last summer.

And now 71-year-old Marilyn Bivens says that her daughter was left so scared from her nasty breakup with Theroux, that she's blaming him and his new wife for supposedly starting their relationship while Justin was allegedly still dating her daughter.

"My baby's heart was pierced. It was a terrible time," Marilyn, holding back tears, told Radar Online in an interview. "Heidi told me what Justin had told her, that something was going to be written about him and Jennifer, that something was going on between them and he wanted her to know that it was nothing, there was nothing to it. Out of his own mouth he told my daughter there was nothing to [the news he was involved with Jennifer]."

If that weren't enough, she also slammed the actor for being "dark and sinister" and claiming that he had a hard time separating his life from the roles he would play on the big screen.

"Being an actor and the parts that you choose to play, you become those characters," noted Marilyn. "You have to enter into everything they are to actually become. I remember once Heidi was speaking about one of his parts, she told him he played it so well and he told her, 'I was that character.' And I thought when you're in that path and continue to change faces and patterns, you become the dark and sinister characters. There are children of light and children of darkness. His world was very dark."

Marilyn even hinted that Jennifer might be a part of her husband's 'dark world' too. "We have a choice, even if you're not a Christian you know what's good; you know the choice of darkness and the people who are acting out that darkness. Justin is married now to Jennifer. They are, I believe, alike in spirit. They complement one another the spirit of the world brought them together."

So far neither Justin Theroux nor Jennifer Aniston have made any comments about the interview.
