New parents ... Anna Faris and Chris Pratt

New parents ... actors Anna Faris and Chris Pratt.

Anna Faris and her husband Chris Pratt are new parents.

The actress, 35, delivered son Jack in the last few days, according to People magazine.

“He arrived earlier than expected and will be spending some time in the NICU [neonatal intensive care unit],” a representative told People magazine.

“The happy parents thank you for your warm wishes and ask that you honor their privacy during this time.”

Although the couple hadn’t revealed their due date, it’s thought baby Jack wasn’t due for a few more weeks.

Faris (The Dictator, Scary Movie) married Parks and Recreation actor Chris Pratt in 2009.

Over the weekend, Nicole "Snooki" Polizzi also became a mum when she gave birth to her son.
