The couple were pictured strolling around New York together on Tuesday, with Bobby placing a protective arm around his newborn son, who he cradled in a baby carrier. Both Bobby and Rose were wrapped up against the winter chill in parka coats and hats as they walked arm-in-arm.

Rose and Bobby surprised fans on Friday after it was revealed they had welcomed their baby boy at the beginning of February. The Boardwalk Empire actor announced the happy news during an appearance on The Late Show with Stephen Colbert on Friday.
"I had a baby on Monday, yes," the actor told Stephen, revealing the newest addition to his family was born on the first day of the month. "You know, I didn't do anything. We [men] don't do anything and I'm so tired."
Bobby also opened up about his first week of fatherhood, and shared the biggest change he has noticed over the last few days.

"I think I've gained 28 pounds since Monday," he said. "I mean, I'm not kidding you. Like, this jacket fit so well, like, last Thursday. But I've been eating so much."
The Blue Jasmine star also delighted fans when he revealed the couple have named their little boy Rocco, adding that his son "is doing great".
Speculation that Bobby and Rose were expecting their first child together first arose in October, after Rose was spotted walking through LAX airport with a hint of a baby bump. That the new parents kept the news of their new arrival secret is not surprising – they are notorious for being extremely private.
Despite being together since 2012, they didn't announce their relationship until 2013, when Bobby confirmed they were dating during his Emmys speech.
He said: "And I want to thank the love of my life, Rose."
