Britney Spears entered a rehab center this week, according to the celebrity news show "Extra." However, TMZ is reporting that Spears has already left the facility.
According to TMZ, the pop star entered rehab at the urging of her family and friends, who were concerned about her hard-partying ways, but refused to stay.
Spears' spokesperson told Access Hollywood, however, that the mother of two is not in rehab, telling Access, "totally untrue. She is not in rehab. No way."
