Shout-out to her big sis — and we really mean shout! Rumer Willis turned 27 on Sunday, Aug. 16, and her little half-sister Mabel decided to give her an adorably loud greeting to remember.
In a video the Dancing With the Stars Season 20 champ posted to Instagram, Mabel, the 3-year-old daughter of actor Bruce Willis and second wife Emma Heming, has a bit of trouble using her inside voice while recording a birthday wish for Rumer.
The little lady, who accessorized her cute yellow T-shirt and blue shorts with a fashionable oversized hat and purple lei, yells, “Happy birthday, Rumer! I love you!” with so much enthusiasm that her head shakes with the effort.
“Best Birthday Message Ever courtesy of my beautiful sister Mabel,” the eldest daughter of Willis and Demi Moore captioned the clip.
But Mabel wasn’t the only sister who Rumer celebrated her birthday with. Earlier on Sunday, the actress, who is set to star as Roxie Hart in Broadway’s Chicago, shared an Instagram of herself and sisters Scout, 24, and Tallulah, 21, laughing in bed together.
“The perfect way to start my birthday…a moment of pure unfiltered joy with my beautiful sisters. I’m so thankful for them,” she wrote of Willis and Moore’s other two daughters. “[They] are the only … few people in the world that make me smile this big.”
Rumer’s Broadway appearance is set to run Sept. 14 through Nov. 1
