Tallulah Willis celebrates two years of sobriety

Demi Moore and Bruce Willis' daughter Tallulah is celebrating two years sober.

The 22-year-old took to social media on Thursday (07Jul16) to share a selfie, in which she is pictured wearing a Hawaiian shirt and sunglasses while holding a candle with the number two on it.

"You know ya (sic) girl got those 2 years clean under her belt," she captioned the Instagram shot.

Her elder sister Rumer Willis later reposted the photo with a caption that included her sibling's nickname, writing, "So proud of my baby Buusk."

Tallulah marked her one-year sober anniversary last year (15) with a party thrown by her middle sister Scout, friend Harold Kuhn, and stylist Maeve Reilly. She shared photos from the party on social media, and wrote, "I am so wholly overwhelmed with love right now I want to cry."

The model and artist, Demi and Bruce's youngest daughter, has previously battled body dysmorphic disorder and depression, and entered a treatment centre for 45 days in 2014, at the urging of her famous parents and siblings.

She revealed in an interview with Teen Vogue last year (15) online bullying was a big contributing factor to her low self-esteem and subsequent substance abuse and body image issues.

"I was in a New York hotel room when I was 13... looking at a photo of myself online. I broke down in tears as I started to read the comments," Talulah confessed. "I thought, I am a hideous, disgusting-looking person. I might be nice and I might be kind, but I'm a really unattractive human being. It wasn't about the anonymous cyberbullies - I became my own worst critic."

Noting her depression hit its lowest point during college, she added, "(The depression) became overwhelming. I didn't sleep or want to talk to anyone, nothing seemed to have a point, the world lost its colour and food lost its taste. I was so removed from my body and from my mind that it was like I was living in a cardboard replica of what life should be."

But thanks to the help of professionals and the continued support of her friends and family, Tallulah was able to pull herself back from her dark days.

"I can say that I'm getting to that place where I'm starting to feel OK with myself, bit by bit. It's not night and day - it's not like now I completely love myself and I have no problems," she told the magazine. "That isn't how it works. But there are the starting points of that, and that's really exciting. I'm growing every day and breaking old patterns."
