• The Musk siblings hated a man Maye Musk was dating so much they put firecrackers in his cigarettes.

• The man was accused of being abusive in Walter Isaacson's biography of Elon Musk.

• Maye Musk dated the man after she divorced Errol Musk, Walter Isaacson wrote.

Elon Musk and his siblings disliked a man their mother, Maye Musk, was dating so much that they put firecrackers in his cigarettes, Walter Isaacson's new biography of the Tesla CEO says.

The siblings' actions caused the cigarettes to explode when he lit them, the book said. The man in question was abusive, the book said, which added that he dated Maye Musk after she divorced her first husband, Errol Musk.

The man she was dating after the divorce wanted her to marry him, but got another woman pregnant shortly after he proposed, the book said. Maye Musk told Isaacson the woman had been a friend who modeled with her.

Isaacson's book, "Elon Musk," details the billionaire's childhood and the strained relationship between his parents. Isaacson wrote that both of Elon Musk's parents were drawn to "dramatic intensity rather than domestic bliss."
