British pop star Robbie Williams still smokes marijuana, despite his past battles with drug addiction. The Angels hitmaker has checked into rehab on several occasions to tackle alcoholism and substance abuse issues, but turned his life around after moving from the U.K. to Los Angeles and meeting his wife, Ayda Field, whom he married in 2010. Williams even quit his 60-a-day cigarette habit, but has now revealed he still smokes marijuana on rare occasions. However, the pop star insists he is careful not to lose control due to his responsibility to his young daughter, Theodora. He tells Britain's Daily Mirror, "The last time I got high was two days ago. Since the birth of Theo I've become less reckless. "I last drank 13 years ago, the last time I got high was two days ago. No big drug sessions, mind, just a small amount, purely to relax. "I'm allowed to go crazy once in a while, just as long as I don't lose control. I have to be there to take care of my daughter, right? That is the good thing - by putting responsibility on my shoulders she is also taking care of me."
