I don't think she's overrated like that. Her popularity just finally spiked after AOL even though she was fairly popular prior to the drama. She wasn't the prettiest out of all the other celebs so she was overshadowed for a long time. She's just taking advantage of her popularity right now to garner more work. But hey, to each their own.
She's had a rather diverse resume compared to a lot of other actresses. She might not be the prettiest girl out there but I think her work resume is pretty impressive. I like her because she's super goofy and I get a kick out of her honesty. Still, to each their own though.
