The singer, who is pregnant with twins, WILL headline the festival in 2018 -- so at least the Beyhivé has that!
In a statement to The Associated Press on Thursday, Bey's Parkwood Entertainment and festival producer Goldenvoice said:
Our hearts are breaking.
It has been confirmed that Cory Monteith's death was caused by a "mixed drug toxicity, involving heroin and alcohol," that was found in his system, according to BC Coroners Service.
As we've reported, Cory was battling with drugs and alcohol over the years and recently completed a stint in rehab earlier this year.
Coroners have contacted the family and have "made them aware of the results."
