Hilary Duff’s 21-year-old ‘Cinderella Story’ co-star Chad Michael Murray wanted to clear up some rumors with Access Hollywood. Hilary and Chad attended The Teen Choice Awards together and Hilary showed up at Chad’s ‘Freaky Friday’ premiere. “You know the minute you guys went together everybody was saying that you’re dating,” Nancy O’Dell told Chad. “She’s a friend. She’s like a little sister. I can’t even look at her that way. She’s younger than my sister. Let’s clarify that now. No, I am not dating Hilary,” revealed Chad.
