Bruce Willis and Demi Moore's daughter Tallulah is celebrating 90 days sober after leaving a rehab treatment centre earlier this month (Oct14).

The 20 year old checked into a clinic on 23 July (14) to deal with reported alcohol and drug abuse problems, and she went home with her mother on 3 October (14).

Willis has now opened up about her progress, revealing she is celebrating three months of sobriety.

In a post on her page she writes, "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 (body) was the best decision I've ever made. Here's 90 more days. Woot woot (sic)!"
