Miley Cyrus has not always been one of my favorites - her antics in the past would regularly make me cringe. But she either grew out of it or wisely realized she didn't need that bag of tricks anymore. Part of those days was this video, where she and her then-Miley and Mandy co-star Mandy Giroux and a couple of others sing about the death of Twitter. It's pretty silly, and Miley is grown-up enough now to post it and give us all a laugh about it.
