The 34-year-old Good Charlotte frontman is currently a judge on The Voice Australia and explained the incident at the Darling Hotel on his Tumblr, writing: "Sunday while I was at work, a hotel employee found a small amount of marijuana in my hotel room. The police were called and responded. Sydney is my adopted home and I appreciate the way the NSW (New South Wales) police handled the situation. They have informed me there will be no charges. I hope this didn't cause too much drama for anyone."
