Demi Moore is about to become a grandmother for the first time.

The actress's oldest daughter Rumer Willis is pregnant with her first child.

Rumer is one of the three children Moore shares with her ex-husband Bruce Willis.

The actress's daughter recently announced her pregnancy on Instagram.

The 34-year-old posed with her boyfriend, Derek Richard Thomas.

Moore reposted the sweet pictures on her Instagram page.

The 60-year-old captioned it with a joke about her plan to be an “unhinged” grandmother.

The snap came months after Rumer's 34th birthday.

Moore marked the occasion with topless pictures of her daughter.
