Antonella's National Anthem?

Antonella Barba, the wannabeen "American Idol" with the racy pics, was recorded while "singing" the Star Spangled Banner at an event that seems to be a high school homecoming or junior high graduation -- which she then posted on her MySpace music page. Rollover Francis Scott Key!

Either nerves got to the winged songbird, or she wasn't sure which country's anthem she was singing -- because when Barba didn't quite know the words, like any pro, she just made 'em up! Genius!

Her mistakes were minor ... like changing "through the

perilous fight" into "ooh the perilous fight," and "bombs bursting in air" to "bombs bursting in there." In where, gurl?! Every song should end on a good note -- although she might not have gotten that memo. Ant ends with "O'er the land of the free, IN the home of the brave!" Classic! Keep those hits coming!
