Earlier this week, Rumer was photographed while soaking up the sun in Los Angeles on Monday, showing off her bare bump while lounging poolside in a tan bikini. She had a big smile on her face as she posed for the camera while sitting on the edge of the pool with her legs dipped in the water. Another shot showed Rumer, who accessorized her look with a white button-down and white sunglasses, placing her hand above her bump as she smiled and stood with a book in her hand.

Moore later shared her daughter's announcement post on her own Instagram, already playing the role of proud grandmother. "Entering my hot kooky unhinged grandma era," Moore wrote alongside the couple's photos. "So happy for you my love!" she later added in the comments.
