Demi Moore can't wait to watch her eldest daughter become a mom!

One day after Rumer Willis announced her first pregnancy with boyfriend Derek Richard Thomas, the 60-year-old actress took to social media to share a supportive snap from one of her daughter's visits to the doctor. 

"Saying hello to the little nibblet!!" Moore captioned her Instagram post on Wednesday, Dec. 21. "Overjoyed for you, my sweet Rumer." 

Rumer is the oldest of Moore's three daughters with ex-husband Bruce Willis. The former pair also share Scout, 31, and Tallulah, 28. 

In the wholesome photo, Rumer is surrounded by her mom and two sisters while laying on the exam table in a doctor's office. Her sister Tallulah appears to be pulling down her face mask to show off a giant smile as she holds on to her big sis' baby bump.
