JOHN GOTTI'S GRANDSON IS MAD AT RICK ROSS FOR USING HIS GRANDFATHER'S NAME THE "TEFLON DON" FOR HIS NEW CD! SAY'S HE SHOULD OF ASKED FIRST!

"Teflon Don" was mob boss John Gotti's nickname. Now it's the name of Miami rapper Rick Ross' new album.
And Gotti's grandson's got a bone to pick.

The Miami rapper should have gotten the okay from his family first, Carmine Agnello, 24, told the Daily News Tuesday.

"My grandfather paid his dues for that nickname. That was my grandfather's life," Agnello said.

John Gotti was dubbed the "Teflon Don" after winning acquittal after acquittal in the 1980s. He was finally convicted of murder and racketeering in 1992.

"He should have asked for permission. A standup, respectable guy would come and ask 'If I could use the nickname,'" Agnello, who is trying to launch a music career under the name Carmine Gotti, said of Ross. "I think he's a great artist, but you can't just start calling yourself that to sell records ...He wants to go for that whole image, but hey, be yourself."

Then he took another swipe at the 34-year-old, whose real name is William Leonard Roberts.

"Only in America can you go from being a corrections officer to calling yourself Teflon Don," Agnello said, noting Ross' former career.

The choice of "Rick Ross" for his stage name also has gotten him in trouble.

Ross is being sued by ex-druglord Ricky (Freeway) Ross for using his name in a copyright infringement lawsuit.

Ross' fascination with the mob didn't start with the album he released Tuesday. His latest mixtapes, also released this year, were called "The Albert Anastasia EP" and "Carlo Gambino." Both Anastasia and Gambino also were mob bosses.

Ross could not be reached for comment.
