Her father Billy Ray Cyrus didn't address the furore directly, but posted tweets about the conflict in Syria and appeared to suggest he thought there were more important topics to talk about.
Her risque performance with Robin Thicke was the talking point of the awards show
"Continue to pray for world peace," one read. "More love… less hate."
His wife Tish who was in the audience as their 20-year-old daughter gyrated on stage in latex underwear retweeted a positive comment from celebrity columnist Derek Blasberg.
He said he was "obsessed" with her routine and likened it to a "karaoke party at the Playboy Mansion. In the 90's. With platform sneakers".
Her family have all posted supportive comments
Miley's sister Brandi also came out in support, telling the Twitterverse: "All else side Miley sounded amazing". She retweeted a comment that said: "I like my superstars with a dash of weird and a little extra spice. And the girl can sing. Consider me team @MileyCyrus."
In the last few months the starlet has made a concerted effort to shed the image she acquired as a teenager playing Hannah Montana, a schoolgirl whose secret alter ego is a pop star. Her long brunette extensions have been chopped off in favour of a peroxide crop and ever increasing numbers of tattoos.
A tempestuous on-off relationship with actor Liam Hemsworth has also kept her very much in the headlines.
Her father appeared to suggest there were more important topics to worry about
The morning after the performance during which she twerked alongside 36-year-old singer Robin Thicke, Miley herself appeared unconcerned. She posted more suggestive pictures of herself to her followers, the Smilers, including one taken in a boys' locker room, in which she's wearing a basketball-themed crop top.
Her attitude hasn't stopped everyone weighing in. The steamy set received more than 4.5 million mentions on Twitter during the two-hour show.
Speaking on TV, Brooke Shields who played Miley's mother in Hannah Montana and has experience of making the transition from child star to adulthood joked: "I was Hannah Montana's mother. Where did I go wrong?"
"She went for it," she said. "You've got to give her some credit. We're all talking about her."
Brooke went on to express concern that her former co-star could be taking attempts to distance herself from her wholesome Disney star days too far.
"I just want to know who's advising her," she said. 'She can sing beautifully, and I feel like if she lets that lead, rather than let her bottom lead....
Her former co-star Brooke Shields is in two minds about her routine
Meanwhile director Judd Apatow posted a picture of her as Hannah Montana with the caption: "'I will always have this version of Miley. Let's live in the past and heal."
Mariah Carey's husband Nick Cannon also made his opinion known, tweeting: "Remind me to never let my kids into showbiz... thanks."
