Investors suing Tesla CEO Elon Musk have argued that his ex-girlfriend, Canadian singer Grimes, may have relevant information about Musk's 'funding secured' tweet on August 7, 2018. The investors cited media reports placing Musk in the company of Grimes, and rapper Azealia Banks, around the time of the tweet. Musk's lawyer said this was an attempt to "sensationalise" the case.
