Most know I am obsessed with reality singing shows in particular 'American Idol', but not anymore.

Just the thought of bringing in Nicki Minaj repulses me, I'm not a fan and I will leave why and my opinion to myself. However, I really did believe it was a matter of time before the video below would happen.

Nicki and Mariah got into a altercation where Nicki threatens Mariah on set, watch the video below that TMZ.com got a hold of and see for yourself.
