Ashton Kutcher says he is proud of former stepdaughter Rumer Willis for speaking up about her painful past growing up in the spotlight and her challenges with body image. Willis, a “Dancing with the Stars” winner, recently penned an inspiring essay for Glamour magazine, revealing how she was bullied because of her looks and her struggles with body image while growing up.

Kutcher, the former star of “Two and a Half Men,” applauded Willis for sharing her inspiring story and took to Facebook to praise her, states E! News. “It's amazing that you're telling your story and speaking up for other women," Kutcher wrote, sharing a link to a post about Willis featured on his A Plus website. The actor further mentioned how Willis is an empowering example for women and young girls by helping them realize that “they don’t need validation from others.”

Willis’ revealing essay recounts her struggles growing up under public scrutiny. The 26-year-old daughter of Bruce Willis and Kutcher's ex-wife Demi Moore admits that she was “constantly bullied” because of her looks and that she “struggled a lot” with her body image. Her essay called for everyone to stop bullying and being cruel. She wrote: “Attacking one another instead of supporting one another has become the norm. Life’s hard enough as it is. Let’s find strength in the fact that we’re different and unique. Let’s allow ourselves to say, “These are my flaws, but I’m still beautiful.” Let’s find our own value, know what we have to offer -- and know that that is enough.”

This isn’t the first time that Kutcher has showed his support for Willis on social media. According to Us Weekly, while Willis was still competing on “Dancing with the Stars,” Kutcher also took to Twitter, encouraging fans to vote for Willis.

Meanwhile, Kutcher is busy balancing personal life and work. He and Mila Kunis have an 8-month-old daughter named Wyatt Isabelle Kutcher, and aside from being a loving partner, father and actor, he is also a producer and an entrepreneur.
