Sarah Palin has nothing to do but pick on singer Christina Aguilera. She calls the pop star an “airhead diva” for singing the wrong lyrics of the National Anthem during Sunday’s Super Bowl XLV.

Speaking to Sean Hannity, Palin said: “Here’s another case of an airhead diva going on TV, running her mouth off, sounding like a fool. She doesn’t understand something so basic about America, yet we’re supposed to tolerate her diva behavior? Americans can see through that, Sean.”

“Unemployment is at nine percent, yet we have to suffer through a performance by a foreigner with a poor grasp of the English language?” Palin argued. “If I were president, I’d deport Ms. Aguilera back to wherever it is she’s from and give Amy Smart a call.”

Wow. Didn’t Sarah Palin know that Christina Aguilera is American? She was born in New York and grew up in Pennsylvania.
