Britney Spears attacks SUV with umbrella

Britney Spears went to ex-husband Kevin Federline's home but after spending 45 minutes ringing the bell to no answer, she was upset.

She was so frustrated that she grabbed an umbrella and attacked a photographer's SUV.

She was later picked up by her mother and brought back to the rehab facility.

Meanwhile, Federline was scheduled to go to court Thursday for an emergency custody hearing in Los Angeles. But the hearing has been cancelled with the pop star back in rehab.
