Presley had started the week in a festive mood, first celebrating what would have been her father’s 88th birthday with fans at Elvis’ Memphis home, Graceland, and later tearfully applauding alongside her mother as Austin Butler received a Golden Globe Award for his portrayal of the King of Rock ‘n’ Roll in Baz Luhrmann’s biopic “Elvis.”

But on Thursday, she suffered apparent cardiac arrest at her home in Calabasas, just north of Los Angeles, and was taken to a local hospital, according to TMZ, the first to report the news. She died hours later.

Although Presley was famous from the moment she was born and a singer in her own right, releasing three albums, she truly leaped into the pop culture vortex with her surprise marriage to embattled pop superstar Michael Jackson and, later, Elvis aficionado and actor Nicolas Cage.
