There must be something in the water at the “Today” show.

Meteorologist Dylan Dreyer announced on-air Friday that she’s pregnant with her first child, just days after co-anchor Savannah Guthrie revealed she’s expecting her second.

Dreyer, 34, and husband Brian Fichera, a cameraman for NBC’s “Nightly News,” are expecting their baby boy in December — around the same time as Guthrie and husband Mike Feldman.

“We weren’t in a rush to have kids and, to be honest, there was a time when we declared we never wanted kids,” Dreyer wrote in a subsequent blog post. “Then one day we both looked at each other and said, ‘I want a baby!’ As usual, we were on the same page and it all just seemed right.”
