Actress Amanda Bynes has distanced herself from party-loving stars such as Lindsay Lohan and Britney Spears, arguing the only thing they have in common is their age group. The Hairspray star, 21, isn't interested in hitting Hollywood nightclubs, and plans to stay as grounded as possible as her career continues to take off. She says, "We're only compared because of our age. Other than that, I never wanted to be a model. I never wanted to be a serious actress. "I'm in no way in competition with them. I feel like I have a totally different thing."
