Jenna Bush Hager is pregnant with her first child, she announced on Wednesday morning's Today show.
"We're so excited and [I'm] nervous as a first time mom, but it's something I always wanted," she told co-anchors Matt Lauer and Savannah Guthrie. "We've been able to keep it a secret ... longer than most."
Bush Hager, a correspondent for the morning program, was also joined on the couch by husband, Henry. "We have so much to look forward to," he said.
As a surprise, the couple then got a live phone call from George W. Bush and Laura Bush. "I'm fired up!" George said. "I could barely contain the news when I found out, so now I can tell my buddies."
So what does the former president want his future grandchild to call him? "Sir!" he joked.
Bush Hager, who married Henry in 2008, is due in the spring. Watch her announcement:
