Savannah Guthrie may have seemed to have first day jitters when she officially debuted as Ann Curry's TODAY replacement Monday, but behind the scenes, she's fitting in just fine with colleagues Matt Lauer and Natalie Morales.

In fact, a source tells Us Weekly Guthrie, 40, is especially close with Morales, 40. At a Tuesday afternoon screening of Dark Knight Rises in New York City, the women — plus Lauer, 54 — checked out the much-hyped flick together.

"Savannah and Natalie were giggly and super chummy with each other as they exited the theater and rode the escalators down to the lobby with a small pack of producer types," an eyewitness tells Us of Morales and Guthrie, who attempted to stay incognito by wearing her sunglasses indoors.

The trio's happy outing comes nearly two weeks after Curry, 55, exited the series after just one year as Lauer's coanchor. Though he made nice with Curry during her final broadcast, an insider tells Us Lauer was "100 percent behind Ann leaving." Off air, Lauer and Curry "were really icy to each other, and she refused to speak to him all week."

On Monday, Lauer was far more upbeat when welcoming Guthrie to Studio 1A's coanchor chair. "You bring a great attitude and what we like to call a weird sense of humor to this program, so we're all very happy to have you," he said.

Joked Guthrie: "It's 7:02 and he's already calling me weird!"
