Lisa Marie Presley is said to have been taking opioids and weight loss medication as part of an extreme weight loss regime in the weeks leading up to her death.
The singer-songwriter was desperately trying to lose weight ahead of the award season and had wanted to "look her best" to celebrate Baz Luhrmann's Elvis biopic.
Lisa Marie had battled with opioid addiction following the birth of her twin daughters in 2008 and previously shared her story in the hope of bringing attention "on this terrible crisis".
