Demi Moore Says She's 'Entering Hot Kooky Unhinged Grandma Era' After Rumer Willis' Pregnancy News

Demi Moore is ready to be a grandma! The 60-year-old "Ghost" actress' oldest daughter, Rumer Willis, announced in an Instagram post on Tuesday that she is expecting a baby with her boyfriend Derek Richard Thomas. Demi posted the same baby bump pics as her 34-year-old daughter, but hilariously captioned the post. "Entering my hot kooky unhinged grandma era," she wrote. Rumer penned "love you mama" in the comments. This baby will be the first grandchild for Demi and Rumer's father, Bruce Willis.
