Jenna Bush Hager cuts hair live on "Today."

Jenna Bush Hager debuted a dramatic bob haircut live on the "Today" show, a style inspired by guest co-host Leslie Bibb. The new look was a significant change for the host. Celebrity stylist Chris McMillan, known for Jennifer Aniston's "Rachel" cut, performed the haircut on set. Hager's daughter and the studio audience expressed reservations during the process, but she persisted. The final reveal of Hager's new hairstyle will be on Tuesday's show, with Bibb and her husband, Sam Rockwell, returning. Hager joked about the change, referencing her co-host Hoda Kotb's recent retirement.
