DO OR DON'T?: There are lots of bridal magazines in the Condé Nast stable, so it might come as a bit of a surprise — at least to their editors — that the Style Network has turned to Glamour for an hour-long TV wedding special airing Saturday. Sure, Glamour is known for its "Dos and Don'ts" feature, but, face it, isn't exactly renowned for its pages and pages of bridal gowns and pretty table settings for the reception. So what gives? Well, according to Salaam Coleman Smith, executive vice president of the Style Network, the magazine is ideal for the cable channel's 18- to 49-year-old demographic. "We have the most affluent female audience in all of cable," she added. Besides, Coleman Smith has a history with Glamour. Two years ago, the Style Network and E Entertainment Television aired "Glamour's 50 Biggest Fashion Dos and Don'ts." Editor in chief Cindi Leive said she still sees reruns from that show, adding the magazine had a bump at the newsstand after it aired. "Glamour's 20 Wedding Dos & Don'ts" will be hosted by Leila Ali, daughter of Muhammad Ali and a recent contestant on "Dancing With the Stars." The show will provide tips from designers including Vera Wang, Monique Lhuillier, Carolina Herrera, Mark Badgley and James Mischka. Style advice will be dished out from Bobbie Thomas, Jay Manuel and Robert Verdi.

And, for the record, Leive's wedding "don'ts" are oversize veils and turquoise and bright purple taffeta bridesmaid dresses. — A.W.

TINA'S TURN: Most first-time authors would be lucky to have one real book party thrown in their honor. For her new book "The Diana Chronicles," about the late Princess of Wales, Tina Brown has at least half a dozen. "David Remnick had one last Thursday," she said Monday night at the fete thrown by Sony Corp.'s Sir Howard Stringer. "I have one in Washington," she said. "Bert Fields is doing one in Los Angeles and Arianna [Huffington] is having a lunch." William Randolph Hearst 3rd is hosting her in San Francisco, and Reuters is toasting her at the Serpentine Gallery in London, which was the place the Princess of Wales showed up the night Prince Charles' affair with Camilla Parker Bowles became public. "It's where Diana wore her famous f--- you dress," Brown recalled. "I guess I have to get a f--- you dress, as well."
