Wilson is the author of the contemporary fantasy novel BloodAngel,[5] published in 2005 by the Roc Booksimprint of Penguin Books. Her second book, Uninvited, was released in 2007 and is an unrelated work intended for young-adult readers. A sequel to BloodAngel, Lord of Bones, was released in 2008.[6] Wilson was one of the first people to use a site like Pinterest to plan out a novel.[7]
In January 2000, Wilson married Elon Musk. Their first child was born in 2002 and died of sudden infant death syndrome (SIDS) at the age of 10 weeks.[1][9] Through in vitro fertilization, she gave birth to twins in 2004 and triplet boys in 2006.[10] On September 13, 2008, she announced that she and Musk were getting a divorce.[11] She and Musk shared custody of their children.[1]
Wilson later wrote an article for Marie Claire detailing ways she thought the marriage was unhealthy, such as Musk's dismissal of her career ambitions, his description of himself as the "alpha" in the relationship, and his pressure for her to become a trophy wife.[1][12] In 2010, she described herself as a "model former wife", and said she was on good terms with Musk's then-wife, Talulah Riley.[13]
She has stated that she kept the last name Musk for the sake of their children.[14] In 2022, one of their twins, officially changed her name to Vivian to reflect her gender identity, and took Wilson as her surname because she no longer wished to be associated with her father.[15][16]
