TMZ has learned a gaggle of paparazzi just took off by helicopter from the Santa Monica airport, headed for Malibu. Their target: Britney Spears in rehab.

Spears checked into the ritzy Promises treatment center in Malibu today. We're told the doors are off the chopper so the paps can get a clear shot of the grounds as they hunt for the troubled singer.
