Hannah Montana, or Miley Cyrus as she's known in real life, isn't actually called Miley Cyrus - she was born with the name Destiny Hope Cyrus. But Miley Cyrus isn't called that now, either.

Sorry, that was confusing. Look - Miley Cyrus, who plays Hannah Montana in the TV show Hanna Montana, has just changed her name from Destiny Hope Cyrus to Miley Ray Cyrus because her Dad is Billy Ray Cyrus and everyone called her Miley Cyrus anyway and she liked the 'Ray' part of her Dad's name.

There, that's cleared all the confusion up.
