After a weeklong "Hoda-bration," Hoda Kotb's final day on 'Today' will be Jan. 10. Kotb's fourth-hour co-host, Jenna Bush Hager, also tells PEOPLE what she will miss most about working with her.

Nearly six years after becoming a literary heavyweight with “Read with Jenna,” she’s starting her own publishing venture with Penguin Random House.

After Kotb departs her longtime role as co-host of 'Today' this week, Bush Hager will be joined by various celebrities.
