Rachel McAdams is a mom!

The Notebook actress secretly gave birth to her first child, a baby boy, with her boyfriend Jamie Linden, Hollywood Pipeline reports.

While no other details are known at this time, including the baby’s name or birthday, the site obtained photographs of Rachel walking with the screenwriter as he appeared to carry their newborn son.

The notoriously private actress managed to keep her baby news under lock and key for most of her pregnancy.

Back in February—just one day after the Oscar nominee skipped the premiere of her latest film, Game Night— E! News was the first to reveal that the 39-year-old was expecting.

Rachel was able to hide her pregnancy for so long by staying out of the public eye.

Before she and Jamie were photographed with their son, Rachel was last spotted at Pearson International Airport in Toronto on November 27 wearing baggy clothes.

The Mean Girls actress and Dear John writer were first linked in April 2016 when they were spotted holding hands.

Keeping with their low-profile relationship, the couple has yet to make their red carpet debut as a couple.

Congratulations to the new parents!
