Earlier this month it was reported that Eilish was in the process of inking a documentary deal with Apple TV+. Though there have been conflicting reports, The Hollywood Reporter cited sources as saying the deal was worth $25 million. The documentary, which was directed by R.J. Cutler, follows the artist after the drop of her massively successful When We All Fall Asleep, Where Do We Go? album. Speaking of Apple, the company's music streaming division named Eilish Artist of the Year. The Los Angeles-born singer and songwriter also performed at the Apple Music Awards.
