Wiz Khalifa and his son.

The bitter split between Wiz Khalifa and Amber Rose continues.

According to TMZ.com, the rapper is preparing to file legal documents requesting more custody of their 1-year-old son Sebastian, because he believes Amber is a bad mother.

Apparently, Wiz has put together a long list of complaints that paint her in a bad light, including:

— Amber often stays out all night, requiring that relatives and staff take over
— The family dog eats its own feces and then licks Sebastian’s face
— When she wakes up she’ll play with the kid for 15 minutes or so and then disappear
— Amber and her mom have a volatile relationship, laced with “shouting matches and vulgar exchanges,” which upset the boy. And during the arguments the “N” word was hurled by Amber’s mom
