Brooke Mueller says she's 9 months sober after she was reportedly questioned in Matthew Perry investigation

Brooke Mueller revealed she's nine months sober during her first interview in 15 years.

Charlie Sheen's ex-wife explained her sobriety journey had "been hard" during an appearance on the "Hollywood Raw" podcast.

"And a lot of people at my level of addiction don't make it," she added. "In fact, most people don't. I worked really hard. It has not been easy. I am sober. I do work a program. I do believe in the Twelve Steps."
