Someone close to Tyga revealed that the rapper snuck his ex Blac Chyna into Kylie Jenner's $2.7 million house while the 17-year-old was away so his baby mama could examine it.

“For weeks, Blac has been worried and nervous about King’s living arrangement at Kylie’s house,” a source told HollywoodLife exclusively. “She’s his mother and she wants to protect him and demanded Tyga allow her inside the house to see what it was giving.”

Tyga's ex is feeling the pressure that Kylie might get everything that she has and had. First, Kylie got Tyga and now she is worried that the reality star may steal her son from her too.

“After weeks of Tyga telling Blac ‘no’ and how disrespectful that would be to Kylie, he finally budged," the source added. "He knew Kylie would be preoccupied with doing things for the ESPYS and he saw that as an opportunity and allowed Blac to come inside when Kylie wasn’t home.”

According to the source, Chyna had fun dissing Kylie's home decor but she approved of King Cairo's room that Kylie built exclusively for him.

Chyna reportedly was concerned about her 2-year-old son after Kylie changed her Instagram name to “King Kylie” as a tribute to King Cairo.

Kylie Jenner and Blac Chyna have one of the most passive-aggressive feuds brewing on social media, but the teen’s Instagram name change from "Kylizzle" to “King Kylie” wasn’t just another subtle diss.

“It’s a tribute to Tyga’s son, King. Kylie had a blast looking after him and chasing him around the basketball court," a source told HollywoodLife. "She can’t count the number of times she said ‘King’ at the game.”

Kylie Jenner is dating Chyna’s ex Tyga, which is the root of their apparent quarrel. The former couple shares 2-year-old son King Cairo together, but the reality star doesn’t want to bring the toddler into their drama.

“Kylie’s issues with Blac Chyna are between the two of them. That precious little boy has absolutely nothing to do with their issues," an insider said. "Kylie would never in a million years drag King into her issues with his mother. Kylie loves that little boy and thinks he’s such an adorable young man.”
