Bruce Willis and Demi Moore's daughter Rumer Willis was crowned the queen of the ballroom as she was named the champion of TV show Dancing With The Stars on Tuesday (19May15).

The actress/singer saw off competition from runner-up, R5 musician Riker Lynch, and third place finisher, model/athlete Noah Galloway, to take home the mirrorball trophy with professional partner Val Chmerkovskiy, who scored his first win on the series.

On Monday's (18May15) penultimate episode, Willis earned an impressive perfect score of 40 for both of her dances, and wowed the judges again on Tuesday's finale for the final performance of the season, a Foxtrot/Paso Doble fusion dance, which also garnered a perfect score of 40.

Throughout the season, Willis received support from her famous parents and their two other daughters, Tallulah and Scout, as they frequently cheered her on from the sidelines.

The entire Moore/Willis family was on hand again for the season finale, with action star Bruce even holding back tears as Rumer claimed victory.

The finale of the 20th season also featured musical performances by axed contestants Patti LaBelle and Redfoo, as well as Jason Derulo, Andy Grammer, Sia, and Fifth Harmony.
