Oscar nominated "Birdman" actor Edward Norton, 45, and film producer Shauna Robertson, 40, named their son Atlas, sources told Us Weekly.
Norton and Robertson got married in a private ceremony in 2012 and welcomed their baby boy in March 2013.
Known for being tight-lipped about his wife and son, Norton is not expected to confirm if his son's name is Atlas any time soon.
Norton is up for an Oscar award for Best Supporting Actor along with "Foxcatcher" actor Mark Ruffalo, "Boyhood" actor Ethan Hawke, "Whiplash" actor J.K. Simmons, "The Judge" actor Robert Duvall.
In 2014, Norton said he had no regrets not reprising the role of Hulk in "The Avengers: Age Of Ultron."
In a recent interview with NPR, Norton said if he had continued on with the Hulk role, he would not have his roles in Wes Anderson's "Moonrise Kingdom" and "The Grand Budapest Hotel" and Alejandro González Iñárritu's "Birdman" because those all overlapped with "The Avengers."
"And those were more the priority for me, but I continue to be a fan and I'm really, really happy I got to do it once," Norton said.
Known for "American History X" and "Fight Club" opposite "Fury" star Brad Pitt, Norton plays a pretentious but very talented theater actor in "Birdman," which is about aging, ego and conflicting approaches to acting.
"I had as much fun making 'Birdman' as I've ever had making a movie. I think it was one of the most creatively satisfying experiences I've had, and I think it's an incredibly audacious and very rare movie," Norton said of the black comedy.
