The former Hannah Montana actress has attracted criticism after stripping naked save for a pair of boots in the video to her new track Wrecking Ball.
The promo premiered just weeks after she was slammed for donning latex underwear for a raunchy performance with Robin Thicke at the MTV Video Music Awards, but Palmer is adamant critics should leave the singer alone.
Giving a speech at Australia's Bigsound music conference, Palmer says, "Let her be. There has to be an allowance for that, otherwise art becomes safe and sanctioned. And it shouldn't be."
