Video: NICKI MINAJ BLASTS MARIAH CAREY “You're a Bitter Old Woman!”

Just when we thought they were getting along on the show, I have cause to believe that Nicki Minaj STILL HATES Mariah Carey and she proved that on yesterday’s show when she went after the diva AGAIN ... calling her a bitter old woman with no personality. Ouch! That hurts……..

Niciki Minaj unloaded on Twitter, following a series of heated exchanges on "American Idol" last night. During the show, Mariah spit a little trash talk Nicki's way and taunted her for never having a #1 single on the Billboard Hot 100. Well, that’s what I call the “Silencer” because Nicki absolutely went DUMB, asin D-U-M-B when Mariah fired the killer shot at her. LoooooooooooooL.


Nicki took some shots back at Mariah on the show -- at one point breaking out a cotton swab and telling Mariah to clean out her ears.

Nicki later continued the war on Twitter last night… telling critics to ask themselves "Why a woman SO successful at her age, is still so INSECURE, and bitter." I’m loving this sha.

Nicki also made a reference to reports that "Idol" producers were recently looking to replace Mariah with former judge Jennifer Lopez:

"All dem #1s but JLo phone ringin? Lol. I guess having a personality, being a secure woman, and giving genuine critique still trumps that." So far, no response from Mariah.
