There's no better way to prove your self-esteem is on the mend than by posting an unflattering Instagram!

Tallulah Willis completed rehab in September for substance abuse and body image issues, and it seems Bruce and Demi's daughter is growing more confident by the day, because not a lot of people would choose to share a snapshot of themselves indulging in greasy french fries and smoking cigarettes while lounging in a bikini!

The 20-year-old celebrated 90 days of sobriety last week, and it seems her time in treatment really changed her outlook on life. "90 days ago i was a mucky mess. things are not perfect by any means but i radiate more postive energy on a daily basis then i ever thought possible. no longer allowing chemicals to infiltrate my bod was the best decision ive ever made. heres 90 more days. woot woot!" she wrote on her social media account.

It's nice to see her so happy and relaxed!
