After being asked if congratulations were in order, Bush said, "Yeah, yeah they are. I have a little one on the way... We're pretty excited. We haven't found out if it's a boy or a girl yet.
"We can't wait. It's the opportunity to bring in a new life and raise a child. I think that's the most special gift to a man and to a woman. So, I look forward to it and to building a family.
"I'm hoping for a boy because if it's a girl, I'm going straight to the gun shop to buy some guns."
