Sources say that Britney Spears has re-entered rehab today. We're not getting our hopes too high, however, because we all know what happened the last time we heard reports that she was checking in to get some help. Once again, we sincerely hope this one sticks, because if Friday's drastic measures and these past few days have taught us anything, it's that Brit's one lost girl who could use a little time out of the spotlight. We will keep you updated as the story progresses, but hopefully this will help Britney finally get her life back on track.

Update: Britney's rep has released this statement: "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."
