According to OK! Magazine on Tuesday, Kylie and Tyga have supposedly been "at each other's throats" as there are major communication issues between them.

A Kardashian family insider says that Kylie and Tyga are basically joined at the hip and that the rapper might be a little jealous of his girlfriend's soaring popularity these days, thanks to her ever changing looks and huge presence on social media.

"Kylie and Tyga have been bickering non-stop lately. It is to the point where it is almost annoying to be around them because they create such an awkward situation," the source said.

The source added, ""Kylie has told her family that Tyga does not approve of the way her career is going and he thinks that she is overexposing herself. He just wants her to slow down and enjoy her life without working all day, every single day."

The couple have managed to cause controversy over the eight-year age gap between them. So far, neither Kylie nor Tyga have made any comments about the report.
