Britney Back In Rehab

Britney Spears is back in rehab. Sources say the singer has checked into an in-patient facility in Los Angeles. The move apparently came after family members, including her mom, pressed her to check in.

A rep for the singer told PEOPLE, "Britney Spears has voluntarily checked herself into an undisclosed rehab facility today. We ask that the media respect her privacy as well as those of her family and friends at this time."

Last week, Spears checked herself into a rehab facility in Antigua but checked out less than 24 hours later.
