Not Prince Jr.? Ginnifer Goodwin and Josh Dallas have been spending the past week enjoying first-time parenthood after welcoming their son on May 29. And now he has a name! On June 4, TMZ reported that the baby's name is Oliver Finlay Dallas (per the official birth certificate). 

Little Oliver was born at Cedars-Sinai Medical Center and delivered by Dr. Paul Crane, who is also the doc who helped out Kim and Kourtney Kardashian with their pregnancies. 

The arrival of their first child comes a month after the Once Upon a Time costars secretly tied the knot in an intimate Los Angeles ceremony. 

Not only do their on-screen characters on the ABC fantasy drama share constant romance, but Goodwin and Dallas also have a palpable connection when the cameras aren't rolling. 

"They really hit it off," a source told Us Weekly back in 2012. "She and Josh have a blast together and had an instant chemistry."
