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. Moore—who brought her chihuahua Pilaf along for the outing—continued in her caption, “It’s an honor to witness your journey into motherhood, and can’t wait to welcome this baby into the world!” Rumer reciprocated the love for her mom in the comments, writing under Wednesday’s post, “So grateful for my incredible lineage of women in my family. I love you all so much. This baby is so lucky to have you guys.” “Also shoutout to Pilaf we couldn’t do it without you,” Rumer quipped in a follow-up comment. The post from the Ghost star comes on the heels of Rumer’s pregnancy announcement on Tuesday, after she and Thomas shared the happy news with a series of sweet maternity photos. “I feel so good, What a joyful hard launch party,” Scout commented on her sister’s post, while Moore chimed in, “LoveYOU ❤️❤️👏👏” The G.I. Jane alum already reacted to Rumer’s baby news on her own Instagram just hours after the announcement, revealing that she is definitely ready to be a grandma. “Entering my hot kooky unhinged grandma era 🌱” she captioned her post on Tuesday. “Love you mama,” Rumer responded in the comments.
