"One of the most beautiful things that I have witnessed is watching the passion become greater than her fear," Demi said. "It has nothing to do with her being my kid or Bruce's kid. It has everything to do with just who she is."
Rumer and her partner Val Chmerkovskiy have dazzled the DWTS judges thus far, skating through to the semi-finals against Noah Galloway with Sharna Burgess, Nastia Liukin with Derek Hough and Riker Lynch with Allison Holker.
Along with Demi, younger sisters Scout and Tallulah will also be cheering on Rumer.
"It's really special that the world is falling in love with her," Scout said.
