Matt Lauer Was 'Friendly' with Former Today Show Colleagues amid Wedding Reunion (Exclusive Source)

Matt Lauer's reunion with his former Today show colleagues went smoothly, a source exclusively tells PEOPLE.

Lauer, 65, attended Today show producer Jennifer Long’s wedding to Reid Sterrett in New York City on Saturday, which also saw Savannah Guthrie, Al Roker, Hoda Kotb, Sheinelle Jones and Craig Melvin in attendance. (Jenna Bush Hager, meanwhile, was out of town for a book event in Maine.)

“Matt Lauer was totally normal, friendly and cordial to his former Today show colleagues at the wedding,” the source says. “There was no awkwardness. They all talked.”

As for how Lauer and Guthrie, 51 — who hosted the show together for five years before Lauer’s 2017 firing — appeared to get along, the insider says, "Savannah gave Matt a hug and they talked for several minutes."

"They were all legitimately happy to be there," the source adds.

The wedding marked the first time the former co-hosts have been photographed at the same public place since Lauer’s termination from the show — a result of accusations of sexual assault against him by former network employee Brooke Nevils, which he has denied.

Several other women later came forward with similar experiences after Nevils broke her silence.

At the wedding, Lauer was joined by his girlfriend, Shamin Abas, while Guthrie attended with her husband, Michael Feldman.

T.J. Holmes and Amy Robach were also in attendance, and the source tells PEOPLE that the couple was “all over each other all night and having a blast.”

Roker, 69, officiated the ceremony between the longtime producer and her now-husband, the source tells PEOPLE, adding that songs such as Lionel Richie's "All Night Long" and ABBA's "Dancing Queen" played.

As for other guests, the insider says they knew that Long and Sterrett were getting married, "but the format was that it was a surprise."

"The theme was ‘yacht rock', " the source adds. "They passed out personalized captains hats to the guests, and the band AM Gold played light rock music."

The insider notes that Kotb, 59, and Guthrie “loved dancing to the band” throughout the night, and Guthrie was among the last guests on the dance floor.
