Turns out Letterman just missed another juicy scoop. Spears went straight from the Ed Sullivan Theater in midtown Manhattan to the nearby Sony Studios, where she faxed her signature to the Los Angeles lawyers handling her divorce. The next day, Nov. 7, the lawyers filed divorce papers at the L.A. county superior court.

The next day a chirpy Spears – still in her platinum wig, plus a snug, low-cut dress and black fishnet stockings – had dinner at the Manhattan restaurant Baldoria with four friends. "She was busting out of her dress," one bartender remarked. "Maybe she's out to celebrate tonight." Sure enough, Spears capped off her merry evening by ducking into a Gap – where she bought $300 worth of winter duds, including a striped cowlneck sweater and a white pom-pom hat – and ice-skating at the Rockefeller Center rink. She smiled as tourists snapped pictures and giggled as she nearly lost her balance before sneaking out a back exit.

A few hours later, Federline made his first public appearance since the papers were filed at Chicago's House of Blues Hotel, where he was quickly spirited from his tour bus through the hotel's back entrance. Says a source at the hotel: "He looked depressed – I actually felt bad for him. He looked down the whole time and didn't make eye contact."
