PHOTO: See Mariah Carey With Full Police Escort after Nicki Minaj threatened to shoot her with a gun

                                     


Mariah Carey got a full police AND umbrella escort on her way out of an "American Idol" photo shoot in Baton Rouge yesterday.

Carey had earlier said that she bulked up her security team after Nicki Minaj allegedly threatened to shoot her with a gun during their blow up earlier this week ... and Thursday she proved she ain't messin' around.
Mariah and Nicki both participated in the shoot -- and even posed for pics TOGETHER. We heard the shoot was peaceful, but it's clear the hatchet is not buried.
