Jane Krakowski is expecting her first child with her British clothing designer fiancé Robert Godley.
A representative for the 30 Rock star confirmed the happy news, saying: "Jane and Robert are indeed expecting a baby.
"Both soon-to-be first-time parents could not be happier!"
Confirmation of the pregnancy comes after Jane, 42, was snapped on a Caribbean holiday sporting what appeared to be a baby bump.
Although her due date is not yet known, it's thought the actress could be in her second trimester.
The announcement comes a year to the day after Jane revealed news of her engagement – although she recently admitted not much headway has been made on the planning front.
"I think we're waiting for that moment where we check out some place and say 'Yes, this is it!'," she said.
"I think because I've been working so much we haven’t had time to look around at what exactly we want to do."
Jane famously starred as Elaine Vassal on Ally McBeal alongside Calista Flockhart from 1997 until 2002.
She currently appears as Jenna Maroney in hit comedy show 30 Rock with Tina Fey and Alec Baldwin, a role for which she has twice been nominated for an Emmy.
