Wiz Khalifa Says Amber Rose has Their Son Living in FILTH, Releases Poopy Pics

                  

Wiz Khalifa is gunning for more custody of his 1-year-old son, because he believes Amber Rose is a bad mom and her home is too dirty and unsafe for their toddler.

Wiz is gearing up to demand an increase in the amount of time he gets with their 1-year-old son Sebastian -- and has released horrible photos from Amber's house which will be part of his case. One of the images, according to TMZ shows dog poop strewn across a backyard patio. One of the complaints from Wiz's camp is that Amber's dog eats its own feces and then licks Sebastian's face.

Other pics include a knife left out on a counter top and loose garbage in the yard.

Amber hasn't responded to TMZ's calls for comment. She's been kinda busy ... much like Wiz. See more pics below
