Rumer Willis, Sisters Scout and Tallulah Get Case of the Giggles During DWTS Rehearsals: Cute Photo!

Rumer Willis sure has some loyal fans! The actress-singer got a visit from her sisters Scout and Tallulah during Dancing With the Stars rehearsals on Tuesday, Mar. 31. The trio simultaneously burst out laughing, which was luckily caught on camera by pro dancer Val Chmerkovskiy.

"The feeling is awesome when you see family celebrate each other," Rumer's partner captioned the Instagram photo. "Love and sisterhood, pride and gratitude for having one another is a very beautiful thing to witness. #thewillissssss @ruelarue @buuski scoutwillis."

Bruce Willis and Demi Moore's daughters sat on the floor in the dance studio during the adorable bonding moment. "Votes are all in. You guys are amazing. Love these sisters," one commenter wrote. A second remarked of the family resemblances: "Rumer and Scout are just like Demi. And Tallulah is Bruce Willis."

Scout, 23, and Tallulah, 21, have been in Rumer's cheering section since the show's premiere on Mar. 26. They joined their famous parents to watch Rumer and Val score a 32 out of 40 for their foxtrot, and have been showing their support on social media ever since.

"Continually blown away by the hard work, grace, and talent of my gorgeous sister. Knew you were going to be good @TheRue but wow wow wow," Scout tweeted on Mar. 30. She added Tuesday: "Obsessed with my sisters."
