Growing up isn't easy to do   Especially for one who always knew   You would always come up second best   Is that why you have such bitterness?      The apple of your father's eye   And always by your brother's side   Then a little sister came along   And you found all the affection suddenly gone      But underneath that cold exterior   I know you've got a heart of gold   So aloof and so superior   But you've got a heart of gold      Watch out, don't get caught in the crossfire   Watch out, still growing up, she's in a rage   I guess she's reached that difficult age      Growing up is very hard to do   Everybody watching your every move   Your private life always on view   But jealously never really suited you      But I know that underneath that rude exterior   There's got to be a heart of gold   Underneath that hard exterior   Is a little girl waiting to be told   You've got a heart of gold   She's got a heart of gold      I couldn't understand your attitude   I only wanted to take a photograph of you   But I was shocked when I heard what you had to say   You picked up my camera and threw it away   I didn't really mean to ruin your day      Now I see you've got a little girl of your own   Little princess suddenly grown   And there's a man, he's smiling at you   He must have been the one who always knew   You had a heart of gold      Underneath that rude exterior   You've got a heart of gold   So aloof and so superior   But you've got a heart of gold      Underneath that rude exterior   You've got a heart of gold   Underneath that hard exterior   You've got a heart of gold      Watch her, she'll give you a broadside   But I know that inside   She got a heart of gold
