After all that time and effort Ivana Trump put into her new, improved look, complete with a Vogue magazine spread, she is in second place on Mr. Blackwell's list of worst-dressed women. Presenting a picture of the dumped Trump in a $200,000 gown, Blackwell described her as "a cross between Brigitte Bardot and Lassie." He awarded first place to rock star Sinead O'Connor, calling her the "baldheaded banshee of MTV" and a "new age nightmare."

Blackwell, the self-proclaimed arbiter of fashion who has been insulting the rich and famous for 31 years, rounded out his list with actress Glenn Close, Queen Elizabeth II, and actresses Julia Roberts, Carrie Fisher, Kim Basinger, Laura Dern, Kathy Bates and Barbra Streisand. Several in Blackwell's Top 10 have been selected by other authors of worst-dressed lists. Blackwell gave his Fashion Fiasco of the Year award to dancer Debbie Allen, whom he called "a hymn to high-tech horror." He did have some good things to say, with his list of Fabulous Fashion Independents: Bette Midler, Sophia Loren, Joan Rivers, Sharon Gless, Texas Gov.-elect Ann Richards, Jordan's Queen Noor, Elizabeth Taylor, the Duchess of York, Michelle Pfeiffer and Liza Minnelli.

Roseanne Barr is angry at the National Enquirer and isn't about to give an inch in her $35 million racketeering lawsuit against the supermarket tabloid. She is back in court with an amended lawsuit, filed Tuesday, in which she accuses the Enquirer of paying security guards, hospital personnel and others to hand over medical records and take unwanted photos of celebrities, which she contends is racketeering. She and her husband, Tom Arnold, filed the original lawsuit against the tabloid in October; the paper's attorneys challenged that claim, saying it failed to meet the requirements of the Racketeer Influenced and Corrupt Organizations Act. The star of "Roseanne" contends that the Enquirer has paid to purloin the property of such stars as Elizabeth Taylor, Tom Hanks and the late Lucille Ball. She alleges that four of her love letters were stolen and published in exchange for "money or other things of value worth in excess of $5,000" ...
