Gwen Stefani stepped out in Beverly Hills on Friday, August 7, just a few days after announcing her split from husband Gavin Rossdale. The 45-year-old rocker flashed no smile as she was photographed getting into the backseat of a car in a parking garage.

The lead vocalist of No Doubt appeared to be still wearing her wedding ring. She looked chic in a red plaid top, ripped jeans, high-heeled fringe sandals and a denim chambray tied around her waist. Her hair was tied in a bun.

Stefani announced on August 3 that she and Rossdale were divorcing after 13 years of marriage. "While the two of us have come to the mutual decision that we will no longer be partners in marriage, we remain partners in parenthood and are committed to jointly raising our three sons in a happy and healthy environment," they said in a joint statement.

Following news of their breakup, there was a rumor saying that Stefani wanted a divorce because she believed Rossdale had cheated on her. Meanwhile, a source told Us Weekly that the coach of "The Voice" was "upset" in the wake of their split. "She really gave it her all and tried to make it work as hard as she could for years. She was in love with him and they had the family she always dreamed of," the so-called insider told the site.
