NEW YORK (AP) — Jenna Bush Hager is pregnant with her second child.

The twin daughter of former President George W. Bush says she expects to give birth in August. She made the announcement Monday on NBC's "Today" show, where she's a contributing correspondent.

Her 2-year-old daughter, Mila, is reportedly excited about the news. Hager told her "Today" show colleagues that Mila has been saying, "Baby sissy, baby sissy."

The "Today" crew presented her with a tiny T-shirt that said, "Baby sister."

Hager, 33, is married to Henry Hager.
