You go girl! Demi Moore's youngest daughter Tallulah Willis celebrated 9 months of sobriety on Tuesday, April 7, marking the occasion with several victorious updates on social media.

"Today marks the day I have kicked 9 months of sobrietys ass," Willis, 21, wrote on Instagram, alongside a photo of her atop Runyon Canyon, fist-pumping with one arm and holding her dog's leash in the other.

The Hollywood scion also shared the news via Twitter, in addition to another photo of her stylish workout gear.

Tallulah’s feat comes amidst another big family moment this past week, when her older sister Rumer, 26, opened up about being bullied in an emotional Dancing With the Stars segment.

"I don't think I really felt comfortable in my body or with how I looked and people were nasty," Rumer recalled on the show. "For years I thought 'Maybe I can get plastic surgery... If I change my face or get really skinny, that will be it, that will be the answer.' And it's not."

Rumer credited Tallulah for bringing her to a place of confidence. "My sister Tallulah was in rehab and I was inspired," Rumer said of her sibling, who was in the DWTS audience along with Moore, grandmother Marlene Willis, and family Glenn Close. "Because she didn't try to hide from it. She really owned it."

The DWTS contestant then dedicated her powerful waltz to Tallulah, and later gave more details to Us Weekly and other reporters backstage about her family dynamic.

"I'm honestly probably the most grateful that I have such an incredibly strong bond with my two sisters," she said of Tallulah and Scout, 23. "One of the best things you can have in your family is the ability to just laugh with each other and spend time and I think that we are able to do that."
