Bickmore and partner Chris Walker have welcomed daughter Evie into the world on Wednesday.

Evie is the second child for Bickmore, who has a son Ollie, 7, with late husband Greg Lange, who passed away five years ago.

Bickmore tweeted out the baby news on Wednesday afternoon.

She was inundated with congratulations from her followers, and colleagues from The Project.

Evie's arrival comes just days after Bickmore joked on Twitter that her unborn baby was "the size of a pumpkin". 

Not sure about this comparing the size of an unborn baby to fruit and veg...hearing it is now the size of a pumpkin is disconcerting! #ouch — Carrie Bickmore (@BickmoreCarrie) March 14, 2015

Back in October, Bickmore announced her pregnancy live on The Project.

The 33-year-old had been in a relationship with Walker, a former producer on The Project, for two years prior to the announcement.

At the time, Bickmore said Ollie was "stoked" that he would soon be a big brother.

The announcement came as a surprise to her co-hosts Matt Doran, Peter Helliar and Steve Price, who later presented Bickmore with a bunch of flowers.

"That was genuine surprise from us because none of us had any idea," Dorman said.
