It looks as though Tori Spelling might have another critic, and this time it's one of her old Beverly Hills 90210 allies, Ian Ziering. The actor reveals in a new interview that he's worried about Spelling and her husband, Dean McDermott and that he doesn't think they should be revealing intimate details of their marriage on their reality television show, True Tori.

Ziering told Access Hollywood that he has mixed feelings about the show, although he doesn't know what's going on behind the scenes, either.

"I have a tremendous amount of love for Tori and, it's just sad. I'm sad," he says. "I don't know what to make of it it's a train wreck, it's a train wreck! And I can't explain it, because I don't know the details.

"I'm just a witness and a bystander, like we all are," he added. "It's like, why is this even happening? Why is this happening on television?"

Ziering also took a jab at Spelling and McDermott for airing their marital problems on national television, but insists that Spelling knows what she's doing.

"It just seems as there is nothing sacred," he continued. "I don't know. But I do know that Tori is a smart girl... she's a smart girl. She knows what she is doing."

Spelling and McDermott hit a rough patch in their marriage after it was revealed that he cheated on her with his Canadian mistress, Emily Goodhand.
