Christina Aguilera enjoyed her last weekend in NYC with her younger brother Mikey and hubby Jordon at the Yankee Stadium. Mikey (who totally must dig having a famous sister) was lucky enough to leave the New York Yankees Vs. Tampa Bay Devil Rays game with Derek Jeters' bat. Christina has been in NYC since starting her Back to Basic tour with a sold out show at Madison Square last month. Today Christina will be making moves up to Columbus for the second leg of her tour.
