Although it seems that things have cooled down between Blac Chyna and Tyga as he congratulated his ex on her engagement to Rob Kardashian in April, it now appears like his greeting comes with a price.

“Tyga’s finances have been up and down over the years. He was hoping to get some relief when Rob married Blac but that just isn’t the case in California where they all live,” a source told Hollywood Life.

Unfortunately for Tyga, just because Chyna is going to be a Kardashian soon, doesn’t mean that he’s excused in doing his duty as a father.

“As long as Blac maintains custody of King, then the amount Tyga makes for child support payments will not change once she gets hitched,” the source added. “Tyga even consulted his attorneys about the possibility of Blac getting a big money TV contract on KUWTK or her own show, but even that would likely have little effect on Tyga’s responsibility towards his son.”

TMZ previously reported that Tyga and Chyna were involved in a bitter custody battle over their 3-year-old son, King Cairo.

The site went on to say that the rapper and his group are trying to destroy Chyna by calling her a “drunk wh*re,” “deadbeat mama” and “nasty b*tch.”

Tyga has allegedly filed legal documents to try to gain custody of their boy and is not letting up. This action is said to be upsetting Chyna especially since Tyga was so openly accepting of her engagement to Rob.

Now that he’s split from Kylie Jenner, who earns a lot more than he does, he suddenly has a change of heart and congratulated Chyna on her second pregnancy.

Us Weekly reports that the rapper took  to Chyna’s Instagram account to congratulate her on the news that she and her current fiance are expecting a baby.
