For the first time it's not tennis star Serena Williams' clothes that have made news. This time it's a pit bull registered in her name that allegedly bit a security guard's buttocks outside her home in Palm Beach Gardens.

However, the wallet in the guards pocket saved him from any serious dog-bite injuries last week, according to a Palm Beach Gardens police report of the incident.

The guard was allegedly nipped by the dog Friday night when the 5-year-old tan pit bull, Bambi, and a white Maltese were roaming around a guardhouse near Williams' home.

According to AP, the guard got the two dogs back to Williams' home using a phone number listed on the Maltese's dog tag.

Williams later told police the dogs got loose after she let them out, but she denied owning the pit bull and told police she was watching the dog for a friend.
