The presenter married fiancé of six years Graham Quinn in a secret ceremony in October, which was attended by just 16 guests.
Klass said that the low-key nuptials had been "perfect" for her, as she didn't want the "pressure" of throwing a wedding that was in keeping with her celebrity status.
'It was one of the most amazing days of my life," she told The Mail On Sunday. "My job is to wear pretty, big, puffy dresses every day and have my hair and make-up done. So I wanted the wedding to be the antithesis of that. I wanted it to be the complete polar opposite of what my working day is like.
"I have never understood why people put so much pressure on themselves for the wedding, worrying about the wrong colour taffeta and the bow being the wrong shape on the back of the dress.
"I think there is enough pressure on people's lives and I didn't want the pressure to be on the wedding day. We just wanted to get on with the actual marriage. So, that is what we did."
Klass added that she was happy to prove that celebrities can have privacy on their big days if they genuinely want it.
"As for selling it and all that malarkey, I don't understand all of that," she said. "I love the excuses people give for selling their weddings. 'People are going to get the photos anyway'. Well, they didn't.
"[They say] 'If you are going to pay all that money out, you might as well get someone to pay it for you'. That actually makes it work and I don't want to work on my wedding day.
"And why do something beyond your means? Why do you have to have the wedding that Grace Kelly had? That doesn't constitute a successful marriage or a good day. That actually just means that you have thrown yourself into hideous debt for 200 prawn cocktails that nobody wanted. Why don't you just have your wedding?"
Klass did accept though that her opinion of married life may not be the healthiest, given how unromantic she can be.
"I am the least romantic person in the world," she confessed. "I have no interest in all that stuff. When Graham came home with flowers on Valentine's Day, I was like, 'Gray, don't get fleeced at Valentine's! I know you love me, just write me a card.'
"I would rather someone show me they love me by the way they actually live their life every day than have these huge gestures of nothing and have someone cheating behind my back."
Klass gave birth to her second daughter with Quinn, Hero, back in March. The couple welcomed their first child, Ava, in 2007.
