Opening up in the latest issue of Lena Dunham's Lenny Letter blog, the former Beverly Hills, 90210 star admits she thought long and hard about including her marriage crisis on the show after husband Dean McDermott cheated on her in 2013, and she finally decided she wanted to be real and face the drama head-on, for all to see.

"This wasn't going away," she explained. "Everyone said, 'This happens all the time. Look at all the A-list celebrities'. They used to complain about it. Then they go on and do a big movie and it just goes away. That's not my life. That's not my relationship with my fans.

"I'm not the type (of person) that can just go from talking about everything and then it's like, 'No personal questions', the next time I do something."

"This was affecting me on many levels, not just the personal level. This is my career; this is, I hate saying it, my brand. All the lines blurred at that point. I obviously ran it by Dean, and if he had been adamant that he didn't want to do it, I would not have done it. I would have respected that. He just said, 'Do what you have to do'."

Tori admits her husband was happy to be part of the show, even though he was "at the lowest point" and "in rehab", adding, "He was just like, 'I f**ked up! I'll do whatever I have to do to maintain our relationship'."

But the actress now feels bad that her husband has become a reluctant reality star: "I feel like I tied him into that world," she explained, "and I feel guilty. All of a sudden, he became Mr. Tori Spelling, and it makes me sad because I don't know what would have happened for him."

The couple worked out its differences on TV with the help of a counsellor and other experts and eventually put Dean's infidelity behind them.
