The American star, 28, married NHL star Mike Fisher in 2010 but said kids aren't on the cards just yet.
She said to E! Online: 'I'm good on the kid front right now. Mike and I are both so busy. We want to do what's best for us and our future children. Anytime within the next few years would just be bad.'
The pair have also yet to decide how many kids they want.
She added: 'I say two but he grew up in a family of four. I just don't know if I can do that. I would probably want to pull my hair out.'
