Hoda Kotb and Savannah Guthrie are the 'Today' show's new anchor team

Hoda Kotb is officially Today‘s new co-anchor.

It’s been a time of controversy and change at NBC’s beloved Today show, but Kotb and Savannah Guthrie aren’t about to let turmoil dent their morning cheer. In an exclusive interview for this week’s issue of PEOPLE, on stands Friday, both are bracingly upbeat — and these women really (really) like each other.

“When you click with someone, man, woman, it doesn’t matter. If it works, it works,” Kotb says of their synergy. “We’re sort of like sisters, and everybody wants a sister.”

That friendship has carried Today through the rockiest period in its 67-year history. On Nov. 29, the show’s star Matt Lauer — a friend of both women — was fired for alleged inappropriate sexual behavior. (Multiple sources describe the cause for termination as an affair that violated NBC’s terms of employment, but in the wake of the news, allegations that included lewd behavior and sexual assault also surfaced.)

Guthrie, 46, and Kotb, 53, broke the news on-air.
