Christina Aguilera, Tim McGraw, Fat Joe, Pharrell Williams and Snoop Dogg are just some of the artists that will be found on Nelly's upcoming albums, "Sweat" and "Suit." Due for simultaneous Sept. 14 release, the albums will be issued on the St. Louis-based artist's own Derrty Records imprint through Fo Reel/Universal.

"Sweat" boasts the Aguilera appearance, where she teams with Nelly on "Tilt Ya Head Back." The disc also includes guest turns by Jazze Pha and Jasper Cameron ("Na-NaNa-Na"); Murphy Lee and Stephen Marley ("River Don't Runnin'"); Fat Joe, Young True and Remy ("Grand Hang Out"), Lil' Flip and Big Gipp ("Boy"); Ali and Gube Thug ("Down in Da Water") and the St. Lunatics ("Getcha Getcha," "American Dream").

The set will also boast a cut featuring Mobb Deep and Missy Elliott, the title of which is yet to be revealed. First single "Flap Your Wings" is No. 45 on Billboard's Hot R&B/Hip-Hop Singles & Tracks chart.

The seemingly incongruous appearance McGraw comes on the second disc, "Suit," where the country superstar teams with Nelly on "Over and Over." Guest highlights on this disc are Williams ("Play It Off"), Jazze Pha and T.I. ("Pretty Toes"), Snoop Doog and Ron Isley ("She Don't Know My Name"), Avery Storm and Mase ("In My Life") and Anthony Hamilton ("Nobody Knows").

That set's first single, "My Place" featuring Jaheim, is a a revamp of Teddy Pendergrass' "Come On and Go With Me." The track is No. 5 on Billboard's Hot Rap Tracks chart, No. 9 on the R&B/Hip-Hop tally and No. 9 on the Hot 100.

"Sweat" and "Suit" follow 2002's "Nellyville," which topped The Billboard 200 and Billboard's Top R&B/Hip-Hop Albums chart and has sold nearly 6.2 million copies in the United States, according to Nielsen SoundScan. The set featured the hits "Hot in Herre," "Air Force Ones" and "Dilemma." A remix album, "Da Derrty Versions - The Reinvention," was released in December 2003, bowing at No. 6 on the R&B/Hip-Hop chart and No. 12 on The Billboard 200.

Nelly will be out promoting the albums with several media appearances, including a performance Friday (Aug. 20) on ABC's "Good Morning America" and appearances on "Pepsi Smash," "The Late Show With David Letterman" (CBS) and "Live With Regis & Kelly" (syndicated). In addition, a Sept. 13 concert at an undisclosed New York location will be streamed live online via AOL's "Broadband Rocks."
