Former President George W. Bush is about to be a grandfather. Bush's daughter, Jenna Bush Hager, her husband Henry are expecting their first child. Bush Hager made the announcement on Wednesday's "Today Show" with Matt Lauer and Savannah Guthrie. "I'm nervous and so excited to say that Henry and I are pregnant," she said. "It's something I've always wanted. I'm a teacher and I love kids." Henry showed up on the show with flowers for his wife. The proud future grandparents were also involved -- the former president and his wife, Laura, called in to the show. "I'm fired up! Looking forward to it," he said. This will be the first grandchild for the former president and first lady.
