Bruce Willis and Demi Moore become grandparents

Their eldest daughter, Rumer, 34, gave birth to a daughter and has already announced her name.

Rumer Willis has become a mother. The actress announced on social media that she and boyfriend Derek Richard Thomas had a baby girl. So Rumer's parents, actors Bruce Willis and Demi Moore, are now grandparents.

"Luetta Isley Thomas Willis. You are pure magic," the new mother enthusiastically wrote under a photo of her sleeping baby girl. "Born at home on April 18," Rumer added. "You're more than we could have even dreamed of."

She previously revealed that she would be happy to give her first granddaughter to her parents. Bruce Willis was diagnosed with frontotemporal dementia in January.
