Gillian Anderson Gives Birth to Baby Boy
This is Anderson's second child, her first with boyfriend businessman Mark Griffiths.
Oscar Griffiths was born three weeks early, but "both he and Gillian are just fine," says Freiberg.
"They are extremely happy – the entire family," she adds.
The former X-Files star, 38, who lives in London, plans to take a few months off before deciding on her next project. She was last seen in BBC's Emmy award-winning Bleak House.
