The 32-year-old socialite has praised the 'Wrecking Ball' hitmaker and insisted the criticism she has come under for her risque image is unfair because she's simply enjoying herself.
She told MTV News: "I think that she's having fun. I think she doesn't worry about what anyone thinks.
"She's having fun. I think she looks sexy. Whatever, she can do what she wants."
Paris is the latest star to come to the 20-year-old singer's defence after her controversial performance - which saw her grinding and twerking routine on Robin Thicke - at the MTV Video Music Awards last month.
Miley's father Billy Ray recently opened up about his daughter's racy appearance at the event, insisting she was only trying to create a "special moment".
He previously said: "I knew that she wanted to do something really special and something everyone would be talking about.
"I knew she'd been putting a lot of practice and thought into what happened in New York."
Meanwhile Miley has claimed her performance was actually edited to make it less outrageous.
She claimed: "I was trying to slap Robin's ass but no one saw it! Believe me! MTV edited so much. They cut almost everything I did. I'm proud of that performance."
