'NSYNC, Britney To Rock Rio

'NSYNC and Britney Spears are heading south, far south, to headline Brazil's third annual Rock In Rio For A Better World.

Spears and the teen pop firm of Fatone, Timberlake, Bass, Chasez, and Kirkpatrick will jet to Rio De Janeiro early next year for the weeklong music festival, which kicks off on January 12, 2001.

Brazilian acts Fernanda Abreu, Pato Fu, and Funk 'N Lata have also been confirmed for Rock In Rio, and a total of 98 bands from around the world are expected to play the festival.

This time around, AOL is backing the fete, which has expanded its title from "Rock In Rio" to the more charitable "Rock In Rio For A Better World." Proceeds from the 2001 event will benefit educational projects from Viva Rio, a preeminent social services organization in Rio helping 11,000 young people.

A staff of 3,000 workers is being brought on to accommodate the roughly 1.5 million people that organizers are expecting over the seven days of the festival.

Concertgoers will find more than 40 hours of music each day spread across three stages.

Tickets for the event will go on sale in October, and organizers are hoping to reach close to 1 billion people in 50 countries through various TV licensing deals.
