Whether or not the former president ends up sharing his moniker with his grandson, Hager says he’s just looking forward to finallyhaving a little boy in the family.

“We had two girls. That’s all he’s ever known,” she tells PEOPLE. (In addition to having two granddaughters, her father is also a proud parent to two daughters of his own: Hager and her twin sister,Barbara Pierce Bush.)

Although Hager shares that her dadabsolutely adores “our girls,”the former first daughter adds that it’ll “be nice for him to have a little fishing buddy as well.”

Of course, choosing a name for their son is just one of many tasks on the couple’s to-do list. “I know I’m far along in my pregnancy, but because we werekeeping it quiet and working on the show, there’s so much I have to do,” Hager tells PEOPLE, revealing that she’s “due in the late summer.”
