Tekashi 6ix9ine BABY MAMA claims he beat her, and broke her jaw

Tekashi 6ix9ine is hoping to get out on bail - but his babys mother Sarah is claiming that he's an woman beater.

Tekashi 6ix9ine is currently in jail facing federal RICO charges. His legal team is hoping to convince a judge to let him out on bail. The rapper's lawyer, Lance Lazarro, tells TMZ ... he's putting a bail package together for the rapper in hopes of getting him sprung from the federal prison facility where he's being held, so he can enjoy some freedom until his trial begins in September.

But with the latest accusations by Sarah, his bail is looking less and less likely.

Last night, Tekashi's babys mother went on a devastating rant on LIVE. The young mother claims that Tekashi's friend - youtube blogger Akademiks - slandered her, and so she made a response video.

In the video, she claims that Tekashi is an abusive man. She claims that Tekashi beat her regularly and one time even "broke her jaw."

Tekashi 6ix9ine has a baby daughter with Sarah, named Saraiyah. They are not currently in a relationship, but they co-parent their child. 

6ix9ine has posed with her as a family on social media and has made reference to them living together in the past. 

Here's the rant:

The plan is to ask the court to set 69's bail at $1.5 million, and Lazarro will also make the case that Tekashi's not a danger to the community - nor is he a flight risk.

6ix9ine's lawyer says he wants to file the motion before his next scheduled court appearance in late January. If the judge rules in his favor and grants bail, the rapper can await trial from the comfort of his own home once he posts the $1.5 mil.
