It has been a big week for Tallulah Willis.

The daughter of Demi Moore and Bruce Willis supported her sister, Rumer, earlier this week on "Dancing With the Stars" and then Tuesday posted an inspiring pic of her celebrating nine months of sobriety.

The picture is of her taking a hike with her dog and throwing her fist in the air in celebration.

"Today marks the day I have kicked 9 months of sobrietys a**," she wrote.

It was just last summer when Willis, 21, revealed insecurities about her looks when she was a teenager.

"I'm diagnosed [with] body dysmorphia," she told StyleLikeU. "[I would be] reading those stupid f***ing tabloids when I was like, 13, feeling like I was just ugly, always. I believed the strangers more than the people that loved me, because why would the people that loved me be honest?"

Around that same time, Willis got treatment for an eating disorder and other issues like depression, according to Teen Vogue.

"While in treatment, I thought a lot about my 5-year-old self. I was a towhead, and my hair stuck out in all directions, like I just got electrically shocked. I had tiny Chiclet gremlin teeth, and I was always running around like a ragamuffin. I realized that I love little me; I adore her and I want to protect her," she told the magazine.
