Celebrity Gossip's

When it comes to celebrity dog-parenting skills, Oprah Winfrey is tops and Britney Spears is the world's worst, according to an online vote by readers of two dog magazines.

"Britney was the overwhelming choice" for worst celebrity dog owner for 2006, Hilary O'Hagan, editor of The New York Dog and The Hollywood Dog magazines, said in a statement.

"She once had three Chihuahuas ... and never left home without at least one of them on her arm," O'Hagan said. "As soon as she met K-Fed and had kids, they (the dogs) disappeared."

Spears has filed for divorce from aspiring rapper Kevin Federline. The 25-year-old pop singer and Federline, 28, have a 1-year-old son, Sean Preston, and a 3-month-old son, Jayden James.
