Oliver Finlay Dallas!
According to their son's birth certificate, filed on Monday and obtained by E! News, Oliver greeted the world on May 29 at Cedars-Sinai Medical Center in Los Angeles, born to mother Ginnifer Michelle Goodwin and father Joshua Paul Dallas.
The proud parents actually had a trial run, having welcomed their second child as Snow White and Prince Charming on Once Upon a Time in the episode "Kansas" this past season as well.
Dallas just tweeted yesterday, "Thanks for all the well wishes about our new baby boy. We are in LOVE! He's our favorite person."
Goodwin, who swapped vows with Dallas on April 12, joked during an appearance on Jimmy Kimmel Live in April about marrying her real-life prince while in her third trimester.
"I married Prince Charming," the actress gushed. "We're both southern, so I was literally barefoot and pregnant at our wedding. I was afraid I would fall over. I don't know what I was thinking!"
