A spokesperson told E! News, "Jenna and her husband do not know whether they are having a boy or a girl."

The rep added, "They want it to be a surprise."

A registry purportedly belonging to Bush and her husband, Henry Hager, lists many in-demand items for any mommy-to-be. The Giggle.com registry, which is listed under the names “Jenna and Henry Hager,” includes goodies such as a navy romper, a kimono top with an elephant print, and a sailor sock set for boys.

Much of the couple’s wish list, including a sleep sheep stuffed animal, an infant car seat, and a video baby monitor, has already been purchased.

Bush, an NBC contributor, announced she was expecting on the “Today” show in December. The baby will be the first grandchild for the former president and his wife, Laura.
