Blac Chyna, Tyga break-up woes seem to escalate as Kylie Jenner's rumored boyfriend is reportedly filing a full custody for their son. The rapper has also slammed Kim Kardashian's BFF after twerking in an Instagram video.

After the Blac Chyna, Tyga's break-up, the former couple is facing another issue particularly on the custody of their son King Cairo.

According to a report from The Hollywood Life, Kylie Jenner's rumored new boyfriend is tired of seeing Blac Chyna partying too hard and leaving their two-year-old son with his nannies.

The rapper also slammed Kim Kardashian's BFF after an Instagram video was posted by Blac Chyna's new pal Amber Rose where she was seen twerking.

A TMZ report said, "[He] thinks his baby mama has lost her focus on caring for the little boy ... she's more interested in making a spectacle of herself ... twerking day and night when there's a camera in sight."

In the video, the gal pals were showing off what they got in the dance floor and were even seen twerking with Rihanna's ex Chris Brown. The "Superhuman" singer is aparently the godfather of King Cairo.

It can be recalled that the Blac Chyna, Tyga break-up made news months ago when the rapper confirmed that he and the model have gone separate ways due to differences.

It also came to a point when Tyga revealed that he is tired of working while Blac Chyna was just partying.

While the rapper may be facing a legal battle with his ex , Tyga seems to be enjoying the company of underage reality star Kylie Jenner.

The "Keeping Up With The Kardashians" star has indirectly confirmed their relationship after posting an Instagram photo of her snuggling on the rapper's tattooed neck and arm.
