Tyga is reportedly talking to his ex, Blac Chyna, even after their split. The rapper is said to be confiding with his baby mama when he and Kylie Jenner have problems.

A report from The Hollywood Life said that Kylie Jenner is not happy that her 25-year-old boyfriend is running to Blac Chyna when they are experiencing a problem. 

The report also said the "Keeping Up with the Kardashians" star is now afraid that Blac Chyna might expose Tyga and Kylie Jenner's relationship through a tell-all book.

"For all Kylie knows, Blac could be taking all that information and plotting to write a book, exposing what goes on behind closed doors with Kylie and Tyga," a source said. "She doesn't trust Blac. She feels that woman has some sort of spell over Tyga, especially since they've had a child together."

The source also claimed that Tyga might get weak around Blac Chyna despite their split last year and that it would break Kylie Jenner's heart if the rapper ditched her for his ex-fiance.

"She wants there to be little to no communication between those two. And whenever Tyga has to drop off King at Blac's house, Kylie will be right there," our source added.

Blac Chyna has reportedly been very aggressive in attempting to pin down Tyga's teenage girlfriend since their split last year.

The former stripper and model usually disses Kylie Jenner in her Instagram posts while imitating the reality star's pouty lips and racy poses.

Blac Chyna and Tyga are co-parents to their two-year-old son, King Cairo.

Despite the issues that surround the relationship of Tyga and Kylie Jenner, the couple is already rumored to be engaged.

They were spotted donning what seemed to be an engagement ring after the rapper called the reality star his fiancée, OK! Magazine told in a report.
