Britney Spears, 'N Sync, Jill Scott, Whitney Houston, Marc Anthony and Shaggy are due to celebrate Michael Jackson's 30th anniversary as a solo artist with a blow-out Sept. 7 concert at New York's Madison Square Garden, Jackson's spokeswoman, Cheri Fine, has announced. The concert is also scheduled to mark a reunion between Jackson and his brothers (Jermaine, Jackie, Marlon, Tito and Randy), the first time that they have performed together since the 1980s. The concert would also be Jackson's first American performance since the late '80s. The event will be taped for TV, said Fine. In a statement, Jackson, 42, said: "I am very excited to celebrate my 30th anniversary as a solo artist with such a distinguished array of talent, friends and fans. I look forward to performing live and reuniting with my brothers on this special night."
