"There's this whole idea of first comes the marriage then the baby carriage so I was so nervous," she said. "My dad was actually really excited because this is the first grandchild for my family. I think somewhere deep inside he was kinda like, 'When am I going to experience that part of life?' Of course he wants us to get married, but for now he was like, 'We're gonna figure this out. Just be happy and have a healthy pregnancy. I'm behind you a hundred percent.'"
