americas got talent (mel b)*We guess new “America’s Got Talent” judge Mel B. learned what NOT to say about contestants. At least contestants in New Orleans.

Seems she got the attention of a lot of boo birds during the taping of the show because she spoke her mind about brass music, according to TMZ.

Mel was in New Orleans Monday, along with Howie Mandel, Howard Stern and Heidi Klum.  The first act of the day was Lagniappe, a very popular New Orleans brass band.

Mel told the band … she’s not a fan of brass music.  Bad move in The Big Easy.  The audience went nuts on her, screaming “Go home,” and “No respect.”

Mel became unglued, and leaned over to Howie, who comforted her.

We don’t think Ms. Mel B. will make that mistake again.
