Miley did it to get tongues wagging, other than her own.
Yes, she tells MTV, she planned the whole thing from the foam finger to the awkward twerking. Her strategy worked. Her performance has become an MTV VMA "moment," like Britney Spears and Madonna before her. She also told Robin Thicke that they're going to "make history." And they did. Her performance has surpassed Beyonce's Super Bowl performance on Twitter for most tweets per minute.
A few highlights:
On the fallout: "What's amazing is I think now, we're three days later and people are still talking about it. They're overthinking it," she says. "You're thinking about it more than I thought about it when I did it. Like, I didn't even think about it 'cause that's just me."
On the haters: "I don't pay attention to the negative because I've seen this play out so many times. How many times have we seen this play out in pop music?"
On her predecessors: "Madonna's done it. Britney's done it. Every VMA performance, that's what you're looking for; you're wanting to make history."
You'll get to hear her talk about it again in her documentary this fall.
