Yesterday Sinéad O'Connor told Miley Cyrus to stop behaving like a dumb prostitute, but in a motherly way. Cyrus replied making fun of her past mental health issues. Now O'Connor threatens to sue the devil child, which has prompted Cyrus to reply with the twattest of tweets:

Sinead. I don't have time to write you an open letter cause Im hosting & performing on SNL this week.

So if youd like to meet up and talk lemme know in your next letter. :)

Can Cyrus possibly get more bratty and annoying than this? Sinéad should meet her for real just to smash her horrible twerking face through a brick wall. Or just wait a couple of years to write Cyrus' obituary, when someone discovers her dead of overdose in some LA motel bedroom.
