Just because Gabriella isn't big in the US, doesn't mean she's not irrelevant. She's pretty big outside the US.
"Sweet About Me" peaked at #1 in Australia and Norway, and went top 10 in Austria, Germany, Netherlands, Switzerland, Belgium, Denmark, Italy, New Zealand, UK, and France. She also went top 20 in Ireland, France, and the UWC.
And she's right. I can't stand to look at pictures of GaGa.
