Rumer Willis Dubs Mom Demi Moore 'Hot Granny' in Loving Birthday Post: '62 Never Looked Better'

'The Substance' actress also received birthday wishes from daughters Scout Willis and Tallulah Willis

Rumer Willis is one proud daughter!

On Monday, Nov. 11, the eldest child of Bruce Willis, 69, and Demi Moore marked her mother’s 62nd birthday by sharing a carousel post of throwback snaps of herself and her mom.

In the first picture, a younger Moore sported her short hair as she carried her then-little girl, Rumer, on her back. The post also featured more snaps of the The Substance star smiling next to her baby, as well as her carrying Rumer on her hip.

“Happy Birthday to the G.O.A.T. @demimoore . I love you so much,” Rumer, 36, wrote. “I am so lucky to have you. You are the funniest, weirdest most specific and kooky Scorpio wild woman.”

Rumer went on to praise her mom in her caption, writing: "This year watching you thrive and explode with love and style and strength has been such a joy to bear witness to. 62 never looked better."

She ended her post by dubbing Moore "hot granny" in hashtag — a nod to Rumer’s 19-month-old daughter Louetta, who she shares with ex Derek Richard Thomas.

In addition to Rumer, Moore shares daughters Scout, 33, and Tallulah, 30, with her ex-husband Bruce Willis, whom she was married to from 1987 to 2000. Both girls also shared tributes on Moore’s birthday on their respective Instagrams, too.

“Happy birthday to my literal SCORPIO MOMBSHELL DEMI F—--- MOORE 🚨🚨 @demimoore,” Tallulah’s caption read, alongside a snap of Moore sporting an animal print leotard.

Scott also shared a carousel of throwback pictures of her mother, including more recent red carpet snaps and photos with her sisters.

“Happy birthday to my constant inspiration, source of unwavering love, guidance, support,” her caption read. “You are my favorite person to travel with, go to a fashion show and then parallel play (me reading, you playing whatever your current favorite little phone game is) in a french hotel room with.”

She added, “I cherish you and every moment that I get to spend with you @demimoore , it’s a privilege to be your daughter.”

Appreciating her birthday wishes, Moore shared a carousel of herself smiling beside balloons and her dog Pilaf. Wrote Moore: "Pilaf says thank you for all the birthday wishes."

Moore has been speaking out on the topic of aging recently as she promotes The Substance, in which she stars as a fictional celebrity named Elisabeth Sparkle who tries a black-market cell-replicating drug the promises to create a younger, better version of yourself. The film has been applauded for taking aim at the unreasonable high beauty standards placed upon women.

Despite wanting to be younger in the movie, which is in theaters now, Moore has said that the film gave her a great appreciation for herself and changed how she felt about getting older.

"I’m at a point where I’m writing my own story, as opposed to my story being dictated to me based on my age," she told Variety in an interview published on Sept. 3. "Who says somebody can’t look a certain way or do certain things? Your 60s is not what your 60s used to be. There’s a part of me that’s enjoying figuring it out as I go along.'

"To me, this is the most exciting time of my life," she added later that month, in an interview on the Today show. "It is. I feel like my children are grown, I have the most independence and autonomy to really redefine where I want to go. I don't know what that looks like or where it is, but I'm just excited to be living in it."
