The basketball championship series is tied between the /*L.A. Lakers*/ and the /*Boston Celtics*/ at three games each.
The Lakers were down 3-2 when Aguilera sang before Tuesday's game at the /*Staples Center*/.
The /*Lakers*/ ended up crushing the /*Celtics*/, 89-67, on Tuesday.
Meanwhile, police and city officials say they have a plan in place for Thursday's game to stop any would-be troublemakers. /*L.A. Mayor Antonio Villaraigosa*/ is encouraging Angelenos to stay home if they can.
"If you don't have a ticket for Game 7, we encourage you to enjoy this time with family and friends," said Villaraigosa. "Save money, save gas, by celebrating at or near your home."
