The Ghost actress shares three adult daughters with ex-husband Bruce Willis—Rumer, 34, Scout, 31, and Tallulah, 28—so it’s been some time since there’s been a baby in the picture. Her eldest, Rumer, announced her pregnancy with boyfriend Derek Richard Thomas on Instagram yesterday, Dec. 21, and several members of the family quickly reposted the news on their own accounts, including Moore. After commenting “LoveYOU ❤️❤️👏👏” on her daughter’s post, the 60-year-old shared the photos on her own page, captioning the carousel, “Entering my hot kooky unhinged grandma era 🌱” The photoset included three black-and-white shots, two of which featured Thomas sitting on the couch and cradling Rumer’s baby bump. In the first, he gave it a kiss as she smiled for the camera and in the third, he lifted his head to offer a look of excitement to the camera. The second was a photo of Rumer’s silhouette against a snowy backdrop out the wall-length windows, framed by several Orchid blooms. “Love you mama,” Rumer commented in response. “I’m into this phase for you,” fellow celeb Gwyneth Paltrow wrote. Michelle Pfieffer, Rita Wilson, Maria Shriver, Lucy Liu, and more also showered Moore with congratulations in the comments. Little sister Scout also reposted the photos, playing off of her mom’s excitement in the caption: “🌱Activating hot, kooky, unhinged Aunt Scout era 🌱,” she began, adding, “Thank you @rumerwillis and @derekrichardthomas for co-creating my new best friend.”
