Chief Keef was 17 when he knocked up Erica Early, who was then 37.

They had a kid in 2013 and it's safe to say things haven't gone well between them since. 

In 2014, there was a warrant out for Sosa's arrest when he didn't pay Early his required child support. They were able to work things out and Keef didn't have to go to jail.

But he may now, as Early has filed new paperwork to have Keef locked up for non-payment. It's unclear how much exactly he owes, but he's supposed to be paying her $2500 a month.

This comes months after Slim Danger, another one of Sosa's baby mamas, hooked up with Keef's rival Tekashi 6ix9ine in an attempt to humiliate Sosa.

Keef has four kids with four different women. And he's only 23.
