Victoria Beckham may be Posh Spice to her fans, but to famed fashion critic Mr. Blackwell, she's the worst-dressed celebrity in the world.

"Forget the fashion spice, wearing a skirt would suffice! In one skinny-mini monstrosity after another, pouty Posh can really wreck-em," he said in a statement.

In 1998, the designer also listed the Spice Girls as the worst-dressed celebs, saying they are "the only spices on the planet that have no taste."

Britney Spears, who often draws Mr. Blackwell's criticism, was spared from the list this year.

"I felt that it was inappropriate at this time to make comment, when her personal life is in such upheaval. I hope 2008 is a better year for her," Blackwell said.

The rest of the top ten worst-dressed stars include:

-- No. 2: Amy Winehouse: "Exploding beehives above, tacky polka-dots below, she's part '50s carhop horror."

-- No. 3: Mary-Kate Olsen: "She resembles a tattered toothpick -- trapped in a hurricane."

-- No. 4: Fergie: "Yes, when it comes to couture chaos, guess it's all in a name!"

Rounding out the top ten are Kelly Clarkson, Eva Green, Avril Lavigne, Jessica Simpson, Lindsay Lohan and Alison Arngrim.
