Their short-lived friendship based around clubbing died hard, but at least crotch shot queens Britney Spears and Paris Hilton are back together in spirit and bad fashion.
Termed "style-free and fashion deprived," Britney and Paris tied for the No. 1 spot on Mr. Blackwell's 47th annual "Worst Dressed" list released Tuesday.
"Two peas in an overexposed pod," Blackwell said of the skimpy attire (if that) donned by pop star Britney Spears, who along with her one-time socialite BFF, Paris Hilton, he accurately dubbed one half of the "Screamgirls."
Some of Blackwell's nastiest words were reserved for Camilla Parker-Bowles, a member of the British royal family, who finished No. 2 on the list.
"The Duchess of Dowdy strikes again," wrote Blackwell. "In feathered hats that were once the rage, she resembles a petrified parakeet from the Jurassic age. A royal wreck."
For nearly five decades, Blackwell, who's no longer an active designer but still an outspoken critic of celebrity fashion, has aimed his poison pen at Hollywood, with young entertainers dominating the list.
At No. 3 was actress Lindsay Lohan, scolded by Blackwell for turning "from adorable to deplorable."
Christina Aguilera was also in Blackwell's fashion hall of shame. He called her a "dazzling singer" but added that she "puts good taste through the wardrobe wringer."
He said actress Sharon Stone resembles "an over-the-hill Cruella DeVille," and Tori Spelling embodies "down and out in Beverly Hills."
Grey's Anatomy star Sandra Oh was faulted for too many beads and bangles.
"She's layered lunacy from head to toe," Blackwell said.
Meryl Streep, who starred alongside Anne Hathaway in the fashion-themed movie, The Devil Wears Prada, came in at No. 10 on the annual dis-list.
"From Streep you could weep," Blackwell said. "Her beauty of a career cannot be denied, but that beast of a wardrobe is pure mother of the bride."
On a kinder note, Blackwell offered his 10 "fabulous fashion independents" - actresses Kate Winslet, Angelina Jolie and Helen Mirren, singers Barbra Streisand and Beyonce, California Rep. Nancy Pelosi, Princess Charlotte of Monaco, model Heidi Klum and actresses Katie Holmes and Marcia Cross.
