Miley Cyrus has said she hopes to still be encouraging women to embrace their sexual freedom when she is 55.
The 21-year-old singer - who just performed a live duet with Madonna for her first MTV Unplugged special - revealed the Queen of Pop has been an inspiration to her as a woman, rather than just a musician.
Miley said: "I hope when I'm her age I'm next to the young up and comer doing whatever it is. I want to always embrace new artists and as I get older I want to continue to evolve with the artists.
"And that's what I think was so cool about Madonna doing that, not looking at me as someone who just looks at her and tries... 'cause I'm not trying to replicate her or be her, we're standing for a similar freedom.
"It's amazing, it's even easier for me than I'm sure it was for Madonna, so I think it's going to get easier and easier as generations go on. I think women are going to be more accepted to be free and embrace sexuality. So hopefully I can be there to encourage that for the artists of the time in 20 years."
The Wrecking Ball star starts her Bangerz world tour on February 14, Valentine's Day.
Miley, who split from fiance Liam Hemsworth last September, said: " Please dear God say it's better than my last Valentine's Day. I told the doorman to go f*** himself on Valentine's Day last year, because he told me happy Valentine's Day and I was just having one of those days. It's true!"
And the former child star insists all she asks for on her rider is the computer game Guitar Hero, which she tweeted a video of herself playing the night of the Grammys.
She said: "I honestly don't ask for much, the only thing I need is Guitar Hero. That's the only thing that gives you something to do for 30 hours on the bus. Hopefully by the end of the tour I'm going to be on expert.
"I had to kind of relearn. I haven't been on tour for two years, so I haven't been playing that much Guitar Hero, so that really is the only thing on my rider."
