Bruce Willis and Demi Moore are officially grandparents! The former couple’s eldest daughter Rumer Willis gave birth to a baby girl last week. She and boyfriend Derek Richard Thomas made the announcement on Tuesday.

“You are pure magic,” the new parents wrote in the caption underneath a photo of their newborn, who they named Louetta Isley Thomas Willis. Louetta was born at home on Tuesday, April 18th.

Rumer and Derek announced their pregnancy in December, and Moore expressed her excitement about her new role in life. “Entering my hot kooky unhinged grandma era,” she wrote in the caption when she reshared her daughter’s announcement.

Rumer’s pregnancy has come at a difficult time for the family, as her father Bruce has been publicly battling frontotemporal dementia. However, despite the heartbreaking diagnosis, everyone has been extremely excited about welcoming a new person into the family.

“[My parents] are so excited. My sisters are so excited, and it’s so fun to be bringing in the first grandkid in our family, especially because we’re such a huge group at this point,” Rumer told People magazine. She added that the excitement has helped her cope with the more challenging moments she’s experienced in the past several months.

“Even those moments that are challenging or feel frustrating, I’m just so excited, that always kind of trumps [everything]… But, it’s wild. It’s the wildest experience, even more so than I ever thought of.”

Congratulations to Rumer and Derek on the arrival of their baby girl, and congratulations to Bruce and Demi on becoming grandparents! May you all enjoy this very special time in your lives. Please share this happy news!
