"Legally Blonde" star Reese Witherspoon has failed in an attempt to prosecute a photographer who allegedly hounded her.

Police informed the popular actress that there was not enough evidence to press charges against the celebrity snappers who encircled her when she left her gym earlier this year, then followed her home to her gated West Hollywood estate.

"I have no doubt Ms. Witherspoon was besieged by the paparazzi that day," says detective Jeff Dunn, head of the Los Angeles Police Department's Threat Management Unit. "But through witnesses and videotapes, we weren't able to corroborate the incident Ms. Witherspoon described."
