Teyana Taylor says Iman Shumpert ignores the safety of their children when they're in his care ... accusing him of smoking weed and being under the influence when he's with them.
The singer takes some shots at the former NBA player's parenting skills in new legal docs from their nasty divorce ... and Teyana's not pulling any punches.
According to the docs, obtained by TMZ, Teyana claims Iman consistently fails to properly care for their two kiddos ... accusing him of failing to feed them despite being in the family home.
What's more, Teyana says Iman smokes marijuana around the kids and is sometimes under the influence when caring for them.
In one instance, Teyana claims Iman put the kids in a rideshare in Chicago and had them dropped off at the United Center alone while he had a private driver take him to the arena.
Add it all up and Teyana claims Iman "consistently demonstrates a clear disregard for the safety of the minor children."
As we first told you, Iman's denied Teyana's claim that he made her feel endangered when she was with him ... and now she's saying he's putting their kids in danger.
