Orlando hitmakers 'NSYNC and Latin pop group Son by Four will join Christina Aguilera, Jennifer Lopez, and Gloria Estefan as performers at the first Latin Grammy Awards, scheduled for September 13 in Los Angeles.

In addition to singing at the inaugural event, Lopez and Estefan will also co-host the show, airing in some 120 countries across the globe, with actors Andy Garcia and Jimmy Smits.

For the Latin Grammys, 'NSYNC and Son By Four will perform a bilingual duet of the 'NSYNC track "This I Promise You" (or "Yo Te Voy A Amar" in Spanish) from its "No Strings Attached" album. Son By Four will then take the lead for an all-star rendition of "A Puro Dolor," the Puerto Rico group's single that topped the "Billboard" Latin charts over the summer.

CBS will broadcast the Latin Grammy Awards live from L.A.'s Staples Center from 9 p.m. to 11 p.m. (ET)

Following the Latin Grammy performance, 'NSYNC will take a few weeks off before gearing up for the start

of its fall tour (see [article id="1432488"]"'NSYNC Retooling Show For Fall Tour"[/article]).

During that off-time, 'NSYNC will continue to mull over its upcoming non-performance-based film project (see [article id="1432497"]"'NSYNC Shoots Concert For Film, Nixes Lip Balms"[/article]), which Chris Kirkpatrick said will likely focus on the individual members of the band rather than the group as a whole.

"I think [the film will] be something we probably do individually," Kirkpatrick told MTV Radio. "Everybody will probably do their own thing to just get the feel for it, and then [we'll] see what happens. I don't think we want to do an ''NSYNCworld'-type movie right now.

"The type

of movie we want to do is something

that expands our abilities and expands our craft," he added. "Anything we do right now, even if it's a great movie, is gonna be judged along with a 'Spiceworld' [movie] or something else that was a little overrated." [RealAudio]

'NSYNC plans to kick off the fall leg of its tour on October 17 in Charlotte, North Carolina.
