This is pretty lovely to see a whole family get on well together despite divorces, re-marriages, new half-siblings, stints in rehab - and all in the spotlight. That's one hell of a family right there.
Tallulah captioned this "#familyportrait #rare" It's still possible though, which is half the battle.
According to Us Weekly: "The whole Willis/Moore clan turned out to cheer Rumer, 26, on as she brought the house down with her super-sexy Disney-themed samba with partner Valentin Chmrkovskiy. Demi Moore, 52, Scout Willis, 23, and Tallulah Willis, 21, were seated in the front row, while dad Bruce Willis, 60, and new wife Emma Heming, 36, sat behind."
A source speaking with the magazine added: "The whole Willis/Moore group was super cute and enthusiastic throughout the whole show. They kept pointing and waving up at Rumer in the skybox and cheering for her. When Rumer did her incredible dance they were all screaming and jumping up and down. Even Bruce was super excited! It was adorable."
And, in case you're wondering who Rumer is meant to be, it's Ursula from The Little Mermaid. See her impressive performance below.
