Paula Abdul's American Idol colleagues - and her attorney - are rallying around the judge as ABC News is planning what's described as a look into "explosive claims" of wrongdoing behind the scenes.
Abdul's camp is so concerned about the report, set to air Wednesday at 10 p.m., that her attorney, Martin Singer, fired off a letter to ABC News warning them to back off unsubstantiated allegations against Abdul.
The exact content of Singer's letter was unknown.
Singer did not return a call Tuesday.
But Abdul's spokeswoman said, "There's a false story that's defamatory to Paula. ... Her lawyer responded to that."
As for ABC's coming piece, she said, "We're not really concerned about any investigations going on."
