Can’t speak for Miley Cyrus (her dad was a mostly awful country singer but I know very little about her). However, Taylor Swift comes across to me as a highly intelligent and business-savvy woman.
If she had any brains she would have not responded to Smiley Virus. You know the old saw...never argue with a fool.
And I haven’t seen one picture of her smashed out of her gourd, flashing her kitty to the paparazzi.
