Celebrity Gossip's

Singer Britney Spears has been voted the World's Worst Celebrity Dog Owner of 2006 in an online poll by "New York Dog" and "The Hollywood Dog" magazines.

Spears won the worst dog owner with fierce competition from last year's winner Paris Hilton, as well as Serena Williams, who recently denied owning her pooch after it bit a security guard, reported a news release from the magazines.

"Britney was the overwhelming choice," said Editor Hilary O'Hagan. "She once had three Chihuahuas (Lacy, Lucky and Bit-Bit) and never left home without at least one of them on her arm. As soon as she met K-Fed and had kids they disappeared."

In an interview with TeenPeople.com in September, before his split with Spears, Kevin Federline said, "We gave all the dogs to friends of ours. It's just too much with the kids and all these dogs running around all over the place. It just wasn't really working."

The winner of this year's World's Best Celebrity Dog Owner was talk show mogul Oprah Winfrey.
