As it turns out, there's only one difference between the actual cast and the one that "In Touch Weekly" magazine dropped last week: SUGAR RAY singer MARK MCGRATH will NOT be on the show, but celebrity chef ROCCO DISPIRITO will.

Mark was in talks to do the show . . . but it didn't work out, for whatever reason. His manager tells "OK!" magazine, quote, "They did talk to us about [being on the show]. We love the show, but it just wasn't something Mark wanted to do."

Regardless, here's the official list of the 13 "stars" . . . along with their pro partners:

("Keeping Up with the Kardashians" minx) KIM KARDASHIAN / Mark Ballas.

(Deliciously gay 'N SYNC stud) LANCE BASS / Lacey Schwimmer. (--Yes, he has a FEMALE partner. Lacey is new to "Dancing with the Stars" . . . but you may remember her as a contestant on last summer's "So You Think You Can Dance".)

(40-year-old soul singer) TONI BRAXTON / Alec Mazo.

(Former "Wild On!" and "Rock Star" host) BROOKE BURKE / Derek Hough.

(Former Olympic gold medal-winning sprinter) MAURICE GREENE / Cheryl Burke.

(18-year-old actor) CODY LINLEY / Julianne Hough. (--Cody played Jake Ryan . . . Miley's boyfriend on "Hannah Montana".) (--For what it's worth, he's the youngest contestant in the history of "Dancing with the Stars".)

(LEGENDARY "All My Children" soap opera minx) SUSAN LUCCI / Tony Dovolani.

(Former chubby NFL star) WARREN SAPP / Kym Johnson.

(Current Olympic gold medal-winning volleyball champ) MISTY MAY-TREANOR / Maksim Chmerkovskiy. (--Maksim took last season off.)

(Actor) TED MCGINLEY / Inna Brayer. (--Ted played Jefferson on "Married . . . with Children".) (--This is Inna's first season on "Dancing".)

(Celebrity chef) ROCCO DISPIRITO / Karina Smirnoff.

(82-year-old former "Mary Tyler Moore Show" actress) CLORIS LEACHMAN / Corky Ballas. (--Cloris is the oldest contestant ever to appear on "Dancing".)

(Corky . . . who's Mark Ballas' dad . . . is a retired competitive dancer. This is his first season.) (If you didn't know, Mark's grandfather, and Corky's dad, George Ballas, was ALSO a dancer . . . and he invented the Weed Eater.

(Comedian) JEFFREY ROSS / Edyta Sliwinska. (--Jeffrey is a chubby standup comic who appears on those celebrity roasts on Comedy Central.)

The "stars" have already begun practicing with their partners. The upcoming, seventh season premieres on September 22nd.
