The 76-year-old Musk called his son fat and said he's not proud of him.

Errol Musk told the hosts of the radio show in Australia that he was not proud of his brother-in-law for being a billionaire. We aren't as if we suddenly started doing something.

Kimbal's brother is Errol's favorite child.

There is more. He urged his son to take a weight loss product after he was asked about the photos of his son on vacation.

He said he has a lot of cars, but not a single one of the electric cars.

He blames his dad for the early struggles of his family. This won't improve it.
