First Pics! Cooper Hefner & Scarlett Byrne Welcome Baby Girl

On Monday, Cooper's wife and “Harry Potter” actress Scarlett Byrne, 29, gave birth to a baby girl, who they named Betsy Rose.

The couple named their daughter after his grandmother Betsy Aldridge-Conrad, who passed away in July. He told People magazine, “My grandmother meant the world to both Scarlett and I.”

He gushed, “We are overwhelmed with joy to share that our daughter, Betsy Rose Hefner, has arrived. We look forward to being home and spending time together as a family in the days and weeks ahead.”

Nearly two months ago, Cooper expressed excitement over his daughter's arrival. Along with posting a pic in her nursey, he wrote on Instagram, “Scarlett is putting a loving nest together in our home in preparation for the little one that arrives in 8 weeks. I took a break from work, slipped my shoes off this morning and asked Scarlett to take this photo in hopes of convincing my daughter in the future that I deserve some of the credit for Scarlett's beautiful work. TBD if I'm successful in this pursuit.”

Cooper and Scarlett announced they were expecting in March. At the time, Cooper shared a photo of Scarlett and her growing baby bump, he wrote on Instagram, “Scarlett and I have been blessed with wonderful news we are ecstatic to share. This summer we will be welcoming a new member to the family. The two of us could not be happier as we wait for the arrival of our little one.”

Scarlett added, “Cooper and I are delighted to share that we have a little one on the way. Our hearts are filled with gratitude and joy, and the two of us can't wait to meet the newest little Hefner.”

The news came just five months after they tied the knot at Ventura City Hall in California. In November, Cooper wrote, “Scarlett and I have made it officially legal and the two of us could not be happier. Cheers to a life full of love, happiness, adventure, and great purpose, Mrs. Hefner.”
