Tesla CEO Elon Musk had a secret relationship with a company executive in his 30s who was 15 years younger than him, and he and the executive were found to have had twins.



The economic media Business Insider reported, citing documents from a Texas state court:



The woman Musk was secretly dating is 36-year-old Sibon Gillies, an executive at NeuralLink, a neuroscience startup she founded.



The two got twins in November last year, and in April this year, they applied for a name change for the children, and a month later, they got the court's permission.



Her request to change her name was to allow her mother's surname to be used in her children's middle names, while keeping her father's surname of Musk.



This is the first time Musk has been revealed to have met with her company executive Gillis.



According to her career, published on job search social media LinkedIn, Gillis serves as Operations Director and Special Protection Officer at Neural Links.



Gillis said she first met Musk in 2015 as an artificial intelligence, AI expert, and from 2017 to 2019 she served as Tesla's AI project lead.



Once Musk completes her social media Twitter takeover, Insider said Jillis is also being talked about as a candidate for her Twitter executive.



Musk married Canadian science fiction writer Justin Wilson in 2008, with whom she split after eight years.



She then went on to marry and divorce British actress Talulah Reilly twice, after which she broke up completely in 2016, and has not been married since.



Musk and Gillis are now pregnant with twins and they have nine children.
