Kristen Bell and Dax Shepard attend regular counselling sessions in a bid to avoid the pitfalls of a celebrity marriage.

The couple wed in 2013, are now parents to two young daughters, and they're determined to keep their marriage on track with the help of a therapist.

Frozen star Bell tells Good Housekeeping magazine, "I thought I had this life thing down pat when I met Dax. I didn’t realise that I needed a much bigger toolbox to have confrontations and disagreements with people.

"You do better in the gym with a trainer; you don't figure out how to cook without reading a recipe. Therapy is not something to be embarrassed about."

And Shepard adds, "We have such different backgrounds, it’s comical. Until I was 32, I thought the world was just wolves, that there was no way anyone was acting with any kind of benevolence. When I met her and her friends, I was suspicious of their unbridled happiness.

"There were hurdles, things she didn’t trust about me, things I didn’t trust about her. I just kept going back to, 'This person has the thing I want, and I have to figure out how we can exist peacefully'. So we started (seeing a therapist together) right away.

"In my previous relationship, we went to couples’ therapy at the end, and that’s often too late. You can’t go after nine years and start figuring out what patterns you're in."
