Tori Spelling's friends apparently think the reality TV star is starring in True Tori out of spite and ultimately for the wrong reasons.

Because Spelling is in the middle of a public cheating scandal that drove her husband Dean McDermott to complete a stint in rehab, a friend of Spelling's told People, "The decision to do this show is not coming from someone who is in a solid, good place. Tori is very, very upset and angry. It's just too raw and personal. There's too much pain and it's too private."

"A part of her wants to completely humiliate him and make him suffer in front of millions of people," the friend added. "She wants to have some sort of justice. She wants him to truly feel the pain of what he did to her."

The couple began filming True Tori, Lifetime's new reality series that will premiere April 22 at 10PM ET/PT, only days after McDermott, 47, left rehab. He had checked himself into a rehabilitation center in January after regretfully having sex with a woman while away on a business trip last December.

True Tori -- which will feature Spelling's perspective on things almost in real-time -- will air only three short weeks after cameras began taping.

True Tori "was all Tori's idea," the friend said. "She's in a total crisis mode. If she can believe that his addiction has nothing to do with her, then maybe they can move on. But there's no way Dean wants to be humiliated on television for cheating on his wife. His life is basically a nightmare."

The series will reportedly show McDermott begging Spelling, 40, to allow him to return to their house after rehab.

"My life means nothing if you're not in it," the friend quoted McDermott saying, according to People.

A source close to the pair, who have been married for over seven years, told the magazine McDermott is currently staying at their house but mainly because Spelling wants him to be a part of their four children's lives.

"They are focused on their kids," the source said. "Tori doesn't consider her and Dean back together."

As for the future of their marriage, "Dean will do anything Tori says right now," the friend explained. "And what better way to ensure that he will never cheat on her after this? I don't think he'd ever want to go through this again."

Lifetime ordered six one-hour episodes of True Tori.
