Rare family portrait!

Rumer Willis‘ mom, dad and sisters have been supporting her all season long on Dancing with the Stars. But on Monday night, they gathered for a quick Instagram photo together.

That’s Rumer, 26, in the back, in her Ursula outfit from The Little Mermaid (it was Disney Night on the show), flanked by dad Bruce, 60, mom Demi Moore, 52 – and younger sisters Scout, 23, and Tallulah, 21, in the front.

Tallulah posted the pic online, acknowledging it doesn’t happen often by tagging the photo #rare.

It certainly brings back the days when the family posed for snapshots like this one back in 2001.

There was plenty for the family to cheer about on Monday, too, as Rumer and pro partner Val Chmerkovskiy earned 39 points out of 40 for their sexy samba set to “Poor Unfortunate Souls” from The Little Mermaid.
