Congratulations, Marie Osmond!

The 56-year-old singer's eldest son, Stephen James Craig, and his wife, Claire, welcomed their second child, a baby boy named Christian Thomas, on Friday, Nov. 27 — making that Grandchild No. 3 for the stunning "Glamma"!

Marie took to Instagram on Tuesday, Dec. 8, to share an adorable photo of the newest addition to her growing family. "Meet my #grandson Christian Thomas! #Love at first sight! ?? #blessed," she captioned the sweet snapshot of the bundle of joy.

“Marie and her husband, Stephen Lyle Craig, are hands-on grandparents," an insider close to the couple recently revealed to Radar Online. The duo are also grandparents to Stephen and Claire's first son, two-year-old Stephen James Craig, Jr., as well as Marie's daughter Rachael Blosil's four-month-old baby girl Rocket Jade.

“Marie has bent over backwards to help both her daughter-in-law Claire and her daughter Rachael," the source continued. "Because she knows how taxing it is to be a new mom.”
