Way to go, Miss Willis!

Demi Moore and daughter Tallulah went for a hike at Runyon Canyon on Sunday to celebrate the 20-year-old marking 90 days of sobriety, and it seems that going through treatment not only made her happier, but it also brought her closer to her famous mom. The pair posted goofy pics with their pooch Meiko on the trails, and it appears to have been an all-around joyous occasion.

"Things are not perfect by any means but I radiate more positive energy on a daily basis then I ever thought possible. No longer allowing chemicals to infiltrate my bod was the best decision I've ever made. Here's 90 more days. Woot woot!" Rumer's sister wrote on her Instagram account.

Tallulah has come a long way since admitting she struggles with body dysmorphia and low self esteem. "I struggled a lot when I was younger. Like I'm diagnosed with body dysmorphia with reading those stupid f--king tabloids when I was like 13 and feeling like I was ugly, like always. I believed the strangers more than the people that loved me because why would the people who loved me be honest?" she explained in an interview with StyleLikeU this past summer.

One day at a time, girl!
