As it turns out, Cyrus had a lot more in store than just her infamous twerking - and things have come full circle, as she's actually hosting the 2015 VMAs. Here's how she got there: Six things that took Cyrus from pop culture punchline to inescapable pop star and social rights advocate.
1. She was unapologetic about the VMAs performance
"I know what I'm doing. I know I'm shocking you," she told Rolling Stone. She explained the same thing to MTV News, which said her performance was called everything from "hyper-sexualized"to "the nadir of American Civilization." She and Thicke wanted to make history, she explained, and viewers were really over-thinking it.
Cyrus also responded to the criticisms that her performance was appropriating from black culture, from the twerking to her back-up dancers. "It's a double-standard. I didn't really realize it, but people are still racist. It's kind of insane," she said. "Like if I had come out (at the VMAs) with all white-girl dancers, and done the (expletive) 'Cha Cha Slide' - same outfit, same everything - it wouldn't have been bad. But because of who I came out with, people got upset."
2. She doubled down on being weird
Confident she had everyone's attention, Cyrus used this time period to officially shed her "Hannah Montana"and Nicholas Sparks-actress persona. And her fans and devotees (or at least her 21 million Twitter followers and 27 million Instagram followers) loved it. She changed her clothing style and hair, sticking out her tongue in nearly every photo. She smoked a joint on stage at the MTV European Music Awards. During her 2014 concert tour, Washington Post pop critic Chris Richards described the scene: "Cyrus rode a giant fiberglass hot dog through the air and pantomimed a sex act with a dude dressed up like Abraham Lincoln. It was a sexed-up episode of 'Teletubbies."'
3. She changed her music
No more squeaky-clean pop songs like "G.N.O. (Girls Night Out)." Cyrus dropped her agent and manager and collaborated with Pharrell Williams on her hip-hop-tinged "Bangerz"album, which featured hits like "We Can't Stop"and "Wrecking Ball." Then came her famous video, where she sat naked - on a wrecking ball, naturally.
She was still criticized for cultural appropriation and Pharrell defended her. "You have to remember this is a 20-year-old evolving. Her dad is Billy Ray Cyrus, her godmother is Dolly Parton and she's raised in an era where hip-hop was king," he said in an MTV documentary. "So when people look and (go) 'Why is she twerking? Why is she doing this?' Because she's a byproduct of America."
4. She became an LGBT rights activist
Pre-VMAs, Cyrus penned an essay for Glamour about why she got a tattoo in support of gay marriage. "When I shared a picture of my tattoo on my Twitter page and said, 'All LOVE is equal,' a lot of people mocked me - they said, 'What happened to you? You used to be a Christian girl!"' she wrote. "And I said, 'Well, if you were a true Christian, you would have your facts straight. Christianity is about love."' Post-VMAs, Cyrus continued to speak out in support for same-sex marriage.
In a profile of Cyrus this year, Paper magazine wrote that "she says she has come to consider her own sexuality - even her own gender identification - fluid." Cyrus talked for the first time about how she's also had serious relationships with women, but the media only focuses on things like her engagement to Liam Hemsworth.
5. She brought a homeless teenager on stage to accept her VMA Award
Cyrus won the coveted Video of the Year at the 2014 VMAs for "Wrecking Ball." But instead of taking the stage, she sent a boy named Jesse in her place, who said he represented the 1.6 million runaways and homeless youth in the country.
"The music industry will make over $7 billion this year, and outside these doors are 54,000 human beings who have no physical home," he said, as the cameras showed Cyrus in the audience with tears streaming down her face. "If you want to make a powerful change in the world right now, please join us and go to Miley's Facebook page."
6. She started the Happy Hippie Foundation
Shaken by the suicide of transgender teenager Leelah Alcorn in December 2014, Cyrus said that was one of the reasons she started the Happy Hippie Foundation, a non-profit that fights "injustice facing homeless youth, LGBTQ youth and other vulnerable populations." To promote the initiative this spring, Cyrus posted YouTube videos of her singing songs with celebrities from Ariana Grande to Joan Jett.
Cyrus told the AP that the money raised will create support groups to help the teens, and also go to My Friend's Place, which helps homeless kids in Los Angeles.
