Following the controversial breakup between Kylie Jenner's rumored boyfriend Tyga and Kim Kardashian's bff Blac Chyna, the former couple is reportedly fighting over son's custody.

According to TMZ, the 25-year-old rapper is not happy with how his baby mama is partying way too much and leaving their two-year-old son, King Cairo with the nannies.

The Instagram video of Blac Chyna twerking with her pal Amber Rose and Chris Brown - reportedly Cairo's godfather - allegedly was the last straw for Tyga to fight for his son's custody.

Hollywood Life's alleged source added, "[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."

While no further details were added about the alleged custody battle, it is safe to assume that's its not going to be pleasant.

Meanwhile, Kylie Jenner and her new boyfriend Tyga, are reportedly going on a date for months now. They have been spotted a number of times throughout L.A. and have reportedly been really into each other despite the eight-year-age gap.

In fact, Hollywood Life mentioned that the rumored couple celebrated Thanksgiving with the Kardashian family.

"Kylie's clearly in awe of Tyga and loves being treated like his princess," the alleged source claimed. "Even though they're just friends. But she has told her sisters many times, 'I can't wait to be 18. The guys my age are lame and don't know how to treat me like Michael Ray does. He's so fine and a perfect gentleman."

Will Kylie Jenner and Tyga's romance flourish despite the rapper's current problems with Blac Chyna? Should Kim Kardashians and the rest of the family worry about their princess' relationship? Sound off in the comments section below.
