Elon Musk's father Errol revealed that he had a secret, seventh child with his stepdaughter.

Like father, like son! Errol (76) spilled a ton of tea in a recent interview with The Sun about his relationship with Jana Bezuidenhout (34), with whom he secretly welcomed an "unplanned" child into the world.

"I haven't checked her DNA. But she looks just like my other daughters," he said.

The two are no longer together, with Errol citing their 41-year age difference as a primary reason.

He also revealed that six other women claim to have children by him. "Obviously they are opportunists," he added.

The South African engineer shares three children with model Maye Haldeman Musk, one of which is Elon, and two with Heide Bezuidenhout, who already had Jana from a previous marriage.

After 18 years, Errol and Heidi split, and in 2017 he fathered a son with Jana, much to the dismay of her siblings.

"They still don’t like it," Errol admitted. "They still feel a bit creepy about it, because she’s their sister. Their half-sister."

Errol, on the other hand, doesn't find it creepy at all. "The only thing we are on Earth for is to reproduce," he explained.

His son Elon tweeted a similar sentiment earlier this month, saying, "Doing my best to help the underpopulation crisis" after it was revealed that he secretly fathered twins with a co-worker while he was together with girlfriend at the time Grimes.

As per usual, the internet has lit up, with many arguing that Errol "groomed" Jana, whom he met and helped raise when she was only four years old.

For Elon Musk, it seems the apple doesn't fall too far from the tree.
