Britney Attends Madonna Concert

Standing by the mixing board during last weekend's Madonna concert in Philadelphia was a lithe young woman, in white spandex pants and white halter top, who looked like Britney Spears. She was Britney Spears. She was ushered in after the house lights dimmed and left before the lights came up.

She wanted a sneak peek at Madonna's Drowned World tour before other A-listers, who are expected to fill New York's Madison Square Garden. (Spears, 19, was 11 years old when Madonna, 42, last toured.) Spears flew in from Florida with five buddies just before the concert and left immediately afterward in a private jet.
