Jennifer Hudson knows a thing or two about "American Idol" ... which is why it's very interesting that she's calling total BS on the war between Mariah Carey vs. Nicki Minaj.
"I don't believe it," Hudson told us at LAX this weekend ... adding, "I think it's just for ratings for the show."
Hudson isn't just a former "Idol" finalist -- she's appeared on the show multiple times over the years ... and even performed on "A.I." back in April.
And Jennifer ain't the only superstar who thinks the judges' feud is fake -- "The Voice" star Cee Lo also thinks the fight could have been staged for publicity.
