The Ghost star reunited with her ex-husband Bruce Willis and joined the couple's two other daughters, Scout and Tallulah, and the actor's wife Emma, to cheer on the 26 year old as she strutted her stuff on the dancefloor with professional partner Val Chmerkovskiy.

The pair's first dance, a Foxtrot, earned the dance duo the highest score of the evening from the judging panel and Moore returned to Twitter after the show to share her excitement and urge fans to vote to keep Rumer and Chmerkovskiy in the competition.

She tweeted, "Been awhile but my baby girl @TheRue was amazing tonight on #DWTS so proud! Watch & vote!"

Proud Moore also shared video footage of the performance with her fans, while Rumer branded the dance, "One of the best moments of my life", in a post on Instagram.

Willis faces stiff competition for the season 20 'mirrorball trophy' from fellow contestants including soul legend Patti LaBelle, LMFAO's Redfoo and actors Suzanne Somers, Willow Shields and Riker Lynch.
