My opinion is that Sinead over-stepped herself so a snarky response from Cyrus should have been anticipated and expected. One also wonders if she's taking the opportunity to grab a bit of limelight, for herself and her cause.
No idea why I'm posting in this thread since I frankly don't give a shit about Cyrus. If she's stupid enough to want to sell her body, it's her life. But since she's being paid a hefty sum, is she really stupid?
