Three men carrying guns invaded the singer’s home at about 2 a.m. on Wednesday.

The armed men forced their way into the house and found Chris’ aunt, put a gun in her face and ordered her into the closet. Law enforcement tells us the home invaders then ransacked the house, took money and other property and fled.

Chris was not home at the time ... instead, he was partying at the Argyle, a club in Hollywood.
