Ashton Kutcher has nothing but praise and admiration for his former stepdaughter Rumer Willis as she prepares for the grand finale of this season's "Dancing With The Stars," reports Hollywood life.

The star took to Twitter to reveal how proud he was of Willis, saying: "Rumer, I'm so proud of you. You are an artist of movement." He also gave props to Willis' partner Val Chmerkovksiy.

Kutcher was married to Rumer's mother, actress Demi Moore, for seven years before they called it quits back in 2012. Despite this, it's clear the former "That's 70s Show" actor has remained close with Moore's daughters with action-star Bruce Willis.
