Britney Spears, 'N Sync, and 98 Degrees will help their fans say goodbye to summer with a special concert event that's being taped next month in San Diego for broadcast on the United Paramount Network as "L'Oreal's Summer Music Mania '99."

Organizers have yet to formally announce a venue or a date for the taping, but other artists slated to perform as part of the show include B*Witched, Christina Aguilera, Tyrese, and Wild Orchid.

MTV's own Bill Bellamy will host the two-hour special, which will also include backstage interviews, a behind-the-scenes look at the concert, and several surprise guest appearances.

"L'Oreal's Summer Music Mania '99" is currently slated to air on UPN stations on August 31 at 8:00 p.m.
