5 years sober today. If you're newly sober, keep at it, it gets so so awesome. YOU CAN DO IT.

The pop-star had earlier said that her life began spiralling out of control in 2005 due to her drinking problems. "I was extremely depressed at the time, that was one of my lowest points. I don't think I ever would have stopped drinking had I not got hooked on Xanax and OxyContin.

"I don't think I was taking them for more than maybe 10 months before I hit rock bottom."
