Duff: Joel will never cheat on me
According to TeenHollywood.com, the singer thinks that his drinking had occasionally caused him to be tempted by female fans, but that sobriety will stop him from ever cheating on her.
She explained: "Joel's so loyal. His dad left his family, and it has made him become the complete opposite. Plus, he doesn't drink anymore. I think there was (a groupie problem) when he was drinking. Now he's clean, so I don't worry about (his cheating)."
