“I’m a mother!” the 33-year-old tweeted on Thursday. “Thanks everyone!”

When a fan told the British model she “won at life” for having a child with Pacey Witter — Jackson’s “Dawson’s Creek” character — she responded, “Even better — with Joshua Jackson!”

A rep confirmed to Page Six this week that Turner-Smith had given birth, telling us, “The couple has welcomed their first child. Both mother and baby are happy and healthy.”

On March 25, Jackson, 41, told “Good Morning America” it had been “stressful” trying to figure out the best way to deliver a baby while in quarantine.

“The medical system right now is a little bit difficult, so we’re figuring it out day by day,” he added.

The new parents have not revealed the sex of their child, but Turner-Smith sparked speculation that she was expecting a girl when she referred to the baby using “she” last month.
