Labor Day weekend was a lost weekend for Christina Aguilera. The "Genie in a Bottle" and "I Turn to You" pop star, 19, lost her voice and had to shut down a scheduled concert Sunday night at the New York State Fair in Syracuse, reports the Associated Press. Then, more than $1,000 worth of merchandise was lost from her tour bag -- including golf clubs, fireworks and a gym bag. (None of the items actually belonged to her, but to members of her entourage, says AP.) Charged with larceny and burglary are two Syracuse University students who reportedly had been partying with members of the Aguilera crew onboard the bus while it was parked outside a hotel on campus. The names of the students have not been released. Aguilera will reportedly try to reschedule the concert for some time in the next two weeks.
