STEPPING DOWN Fidel

• You're unwelcome: Giorgio Armani dis-invites New York Times fashion diva Cathy Horyn from his Milan show at the last minute. Seems he's still pissy about some fairly tame stuff she wrote about his Paris couture show last month. Maybe Giorgio needs to impeccably tailor himself a thicker skin.

• Final fantasy: Hottie threesome Johnny Depp, Jude Law, and Colin Farrell are in talks to step into Heath Ledger's Converse All Stars, playing different versions of Ledger's character in his final, unfinished film, Terry Gilliam's The Imaginarium of Doctor Parnassus.

• Day in court: In conspiracy news, Mohamed al-Fayed, father to Dodi, has his big moment in the Princess Diana inquest. Al-Fayed took the opportunity to implicate Prince Charles in the death of Diana, saying his highness helped plot the princess's death so he could marry "crocodile wife" Camilla Parker-Bowles. For good measure, he called Prince Philip a "Nazi" and a "racist."

• No deal: After six days in court, Sir Paul McCartney and Heather Mills fail to reach a financial settlement in their divorce case. A judge will now decide just how much Beatles booty Mills walks off with.

• Undressed to impress: Lindsay Lohan goes nude in a Marilyn Monroe-inspired shoot for New York magazine's fashion issue. Insert tasteless joke about carpet matching the drapes ... as if Lilo had carpet.

• Sex-less tape: First, Romo-gate, now this: Jessica Simpson and Papa Joe are being sued by a fitness video company for blocking the release of a fitness vid she made during a "career lull" in 2005.

• Plagiarization nation: Happy Wisconsin Primary Day! Hillary Clinton's camp celebrated early yesterday, accusing rival Barack Obama of plagiarizing a few lines in a speech he made in Milwaukee over the weekend.
