Should've known this would happen. It wouldn't have been surprising if she HAD died, considering all the stress Andrew's given her in the last couple of weeks, and her age. But yeah, I won't believe she has until it's on proper news sites and not just social media.
That 8am thing is false, by the way. An article from a couple of years ago about a Queen's death hoax says this:
Not everyone is aware of the debunkers, and many are mistakenly under the impression that news of a royal death could only be announced at 08:00, and that was the reason for the delay.
