The 29-year-old, who married hockey player Fisher, 31, in 2010, said she doesn't have to worry about her husband and trusts him blindly, reported Contactmusic.
"We're both independent people, so we can't have somebody around 24 hours a day, seven days a week. The drawback is that we can go weeks without seeing each other. But he's the only guy I've never had to worry about.
"Any guy I've ever dated, there would always be that doubt: 'He didn't answer his phone. What's he doing? It's late.' I'm not the crazy-girlfriend type, but there was a little voice in the back of my head. I don't have to worry about Mike," she said.
