Kristen Bell experienced "trust issues" in the early days of her relationship with her fiance Dax Shepard after discovering he had battled alcohol and drug abuse.
The actor has been sober for eight years and began dating Bell in 2007, but she was shocked when she found out about his past.
In a joint interview with newsman Piers Morgan, Bell was asked if she knew about Shepard's past when they met and replied, "Not when we first met, no. I met him and he was my prince charming.
"Then a few months in, this is sort of what challenged us a little bit and created some trust issues... you know, you start to find out flaws about your partner a few months in. If you're really, really drawn to them, you don't know necessarily how to react to that.
"I grew up in a very conservative household, and very much... Catholic high school as a goody goody. And I never experimented with drugs. And I don't have that past."
Opening up about how he beat his issues, Shepard adds, "My only obsession that was stronger than that was working. I'm probably more addicted to that than any other thing. So I would get sober for movies. And then in between those movies, I would go and find myself in some dangerous situations.
"So I got sober for this movie I did eight years ago. And luckily after that movie ended... I had some moment where I was able to go, I don't want to keep doing this. I probably won't survive another few breaks between movies.
"I didn't get sober as a hobby. It was more of a necessity."
