Who'd have thought that Princeton grad and sometime actress Brooke Shields would end up on the cover of a special issue of Outlaw Biker magazine? But there she is, in leather jacket and helmet, perched on the back of a Harley-Davidson clutching a 420-pound biker known only as "Boda."

According to the magazine, the 22-year-old Shields had been taping a television special in North Carolina when, accompanied by her mother and bodyguards, she turned up at a topless bar and biker hangout in Fayetteville. Boda is quoted as saying that Shields wanted a ride and "I was the only sober person around so I became the logical choice." With borrowed jacket and helmet, Shields took off on the 30-minute adventure, during which Boda cranked the Harley up to 95 mph. "I figured if the cops stopped me," Boda said, "I'd just show them who I was packing, and they'd understand. Hell, she loved it! She just hung on, smiling, with her arms round me and her chin on my right shoulder." A spokesman for Shields did not dispute the account and added only, "We're saying no comment."

The Duke's Domain

It's nice to know that Andrew and Fergie are about to get a place of their own. Continuing to live off the in-laws or in rented digs simply won't do, so the couple, sometimes known as the duke and duchess of York, have asked permission to build a two-story home near Mom's house, Windsor Castle.

Fortunately for the young couple starting out, Mummy will pay the estimated cost of $825,000. The two-story gabled abode will be built in a walled garden of Sunninghill Park, 22 miles west of London. This is the site of an 18th-century house that burned down in August 1947, three months before it was to have become the first home of Andrew's parents, then-Princess Elizabeth and her new husband Prince Philip, following their wedding.

Out and About FirstLady Nancy Reagan was out for lunch again yesterday with friend and dining companion columnist George Will. They spent 2 1/2 hours at the Old Angler's Inn out toward Great Falls in Maryland. Assuming the golden afternoon would entice the couple to dine outside, an isolated table was set for them. Because of the splendid weather, however, everyone was eating outside, and Mrs. Reagan and Will chose instead to eat alone in the second-floor dining room. Mrs. Reagan had an avocado shrimp salad. Will had swordfish with mustard sauce. Both had two glasses of Perrier ...

The Kamber Group, a hot Washington public relations firm whose clients include a number of labor unions, has come up with a new gimmick to attract customers. Vic Kamber is running newspaper ads across the country listing the names of such public relations giants as Hill & Knowlton, Burson-Marsteller and Rogers & Cowan with a line struck though their names and an accompanying message: "Look for the Union Label." The sell is "If you won't print nonunion, why communicate nonunion?" That could set off a new kind of public relations warfare, especially for politicians ...
