Guthrie and Mike Feldman, a 45-year-old communications strategist, tied the knot Saturday near her hometown of Tucson, Ariz. It was there she told her guests she's four months pregnant.
Guthrie's on-air "Today" colleagues were among those on hand for the wedding ceremony.
The marriage-and-baby twofer was revealed to the rest of the world on Monday's edition of "Today," with Guthrie back in New York at the NBC morning show.
Beside her at the anchor desk, Matt Lauer reported she was "a beautiful bride."
The 42-year-old Guthrie said she was happy to go public with her pregnancy, because "I can't suck in this gut anymore."
