"I'm so ready to hold my baby girl—I'm going to be a very hands on mom," she told Hello!"I'm thrilled that I am having a girl first because I feel like I know a lot about raising a strong woman. I feel very empowered myself and I think my daughter will, too," she continued. Hayden also gushed about her fiance, saying, "He's such a resilient guy. He's so calm and patient. I have never even heard this man raise a voice." While the blonde beauty is ready for her new addition, she's not saying "I Do" just yet.
