Apparently, the Los Angeles Lakers think X-Tina is a good luck charm. I am totally team Lakers!  The Los Angeles Lakers are hoping for some more luck from Christina. Aguilera was chosen to sing the national anthem for the deciding Game 7 of the NBA Finals. The basketball championship series is tied between the 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 in Los Angeles. Christina x2 tonight in La La Land. I cant stand anything Boston…since I am a HUGE New York Yankees fan…soooo….Let’s Go Lakers!!
