Tone-deaf “American Idol” judge KARA DIOGUARDI – ignoring my wake-up call that she’s toast after this season because SIMON COWELL and the other judges can’t stand her pushy ’tude – got all up in producers’ faces, complaining she looks drab and unglamorous next to PAULA ABDUL and wants her wardrobe budget increased.

Exasperated execs repeated what I told you months ago – Kara and Paula must split the $100,000 wardrobe budget 50-50, period!

Crazy-like-a-fox Paula, of course, beats the budget ban and looks on-cam glam because she doles out her own dough for designer duds!

So don’t be dumb, DioGuardi. You’ve got almost no hope of making it to next season, but spend what it takes to get gorgeous – fast!

Then cut the endless yapping, chill the ’tude and… who knows?

Stay tuned.
