R&B singer Monica did her thing last night (Tues. Jun 8) as she performed the National Anthem before Game 3 of the 2010 NBA Finals match up between the Boston Celtics and the Los Angeles Lakers in Boston, MA at the TD Bank North Garden (Check out our recap of the game here).

The performance was great, though we could have done without the surprise appearance from the back-up singers. Mo could have taken on that whole song by herself. The background singers kind of threw us off a bit, but still a great performance never-the-less.

Check a few out pics of Monica at Game 3 of the NBA Finals 2010 Game in Boston below and continue reading for video footage of her flawless performance of the “Star Spangled Banner”…
