While fans usually carry a torch for their favorite boy band member, lately it's been the other way around.

Kevin Richardson became the second Backstreet Boy to run the Olympic Torch Relay on Tuesday, and 'NSYNC's Lance Bass also joined in on the effort.

Richardson, promoting his Just Within Reach environmental foundation, carried the flame for three blocks on Figueroa Street in downtown Los Angeles.

Bass, chosen by relay organizers for his work with 'NSYNC's Challenge for the Children organization, which benefits children's charities, ran several blocks in Newport Beach, California.

In December, Backstreet Boy Howie Dorough carried the torch in Florida for his Dorough Lupus Foundation. His sister, Caroline Cochran, died of the disease in 1998 (see "Backstreet's Howie Addresses Loss Of His Sister").

The Olympic Torch Relay, an Olympic tradition since 1952, began on November 19, when the torch was lit in Olympia, Greece. It will be carried to the Winter Games in Salt Lake City, Utah, next month.

Richardson launched the Just Within Reach Foundation a year ago to provide environmental education and promote personal responsibility with regard to the health of the planet.

'NSYNC are scheduled to perform at Olympic Medals Plaza on February 23 and during games' closing ceremonies (see "Creed, 'NSYNC, Dave Matthews Band, More Set For Olympic Concert Series").
