What split? Rob Kardashian and Blac Chyna are back together after a "heat of the moment" separation. Um WTF?
"He apologized to her on the phone," a source close to the 28-year-old model tells Us. "She was just sick of him and his behavior. She had it with his insecurities and jealousy."
We give up trying to keep up with these Kardashians, srsly.
