MALIBU, Calif. —  A photographer was shot in the leg with a BB gun outside a home where he believed Britney Spears (search) was attending a bridal shower Saturday evening, authorities said.

It was unclear who fired the BB as the photographer was staking out the event at the Malibu home, sheriff's Lt. Steve Smith said. He said firefighters bandaged the man's leg and he went to a hospital.

"It could've been somebody driving by, walking by, we have no idea where it came from," Smith said.

The photographer, identified as Brad Diaz (search), was about 200 yards from the home outside the home's long driveway when he was hit, Smith said. He was one of about 10 photographers standing in the street.

Smith originally said the home belonged to Spears, but said deputies later learned that it belonged to someone else and that Spears is a frequent guest. He did not identify the owner.

A message left with Spears' publicist was not immediately returned Saturday night.
