Tyga not happy with Blac Chyna calling their son 'ugly'?

Rapper Tyga is reportedly upset with ex-fiancee Blac Chyna after she called their four-year-old son King Cairo 'ugly' on her social media post.
Chyna, 28, shared a video on Instagram, dancing on "Juju on That Beat" and lip-syncing the lyrics "You ugly, you yo daddy's son", while approaching her son King Cairo.
The model later giggled, indicating that she was just kidding. However, Tyga apparently did not find the joke funny.
"Tyga is not cool with Chyna calling King ugly, joking or not. He thinks Chyna's a really good mother, but made a big mistake with saying what she did and then an even bigger mistake by posting on social," a source said.

"That's just way out-of-pocket and King is a highly intelligent kid, who remembers everything and Tyga's certain he'll remember this. If she wants to come at Tyga and shade him that's one thing but he doesn't want her to be using their son to do so," the source added.
