The 26-year-old actress was spotted sitting on a stoop and smoking a cigarette while reading a book, reported Us magazine.
She was spotted at a treatment facility, few days afterwards in Utah, not wearing the diamond ring that her fiance of three years, the Ukranian boxing champ, Wladimir Klitschko gave her.
This was a second visit to the rehab for the "Nashville" actress, who previously sought treatment in October 2015 after welcoming her daughter, Kaya in December 2014.
