WTF! ANITA BAKER CHOPPED THE NATIONAL ANTHEM LAST NIGHT AT THE NBA FINALS!

Francis Scott Key is probably turning in his grave.

Anita Baker belted out a rendition of the "Star Spangled Banner" Thursday night before the start of Game 4 of the NBA finals, but the R&B singer fell short of hitting the song's key notes.

The 52-year-old throwback singer started off a little shaky before the performance nosedived as Baker sung, " … And the rocket's red glare."

Things only got worse for Baker as she stumbled through the song's closing, failing to nail the finale.

The social-networking Web site Twitter lit up after the performance as viewers likened her rendition to a dying cat.

"I love her and all," one user tweeted, "But y (sic) does Anita Baker sound like a dying cat singing the Star Spangled Banner!?"

Another user said, "NBA Finals Where Amazingly Terrible National Anthems Happen … I love you Anita Baker but what the hell was that?"

Eventually, "Anita Baker" began trending on Twitter as viewers continued to express their shock at the performance.

Her appearence before the Lakers and Celtics took the court was a far cry from her best known work. Baker won her first Grammy for Best R&B Vocal Performance for a female in 1987 for "Rapture."

The Ohio-born singer went on to win eight Grammys over the course of her career, and she released her last album in 1994 with "Rhythm of Love."
