Video: Christina Aguilera Butchers the National Anthem at Super Bowl XLV

Xtina sings "The Star-Spangled Banner" before kick-off.

Christina Aguiera took center stage at Dallas Cowboys Stadium for the Super Bowl XLV Pregame show of the national anthem. The 30-year-old Pittsburgh native—who's been singing "The Star-Spangled Banner" for the team since she was just seven years of age—flat out butchered it this time around. Since she's one of the few Pop chicks who can actually sing and has an amazing voice, we'll give her the benefit of the doubt. Watch Xtina's screw up above.
