I should've seen it comin'
  I should've seen it comin'
  I should've seen it comin'
  
  My sister
  Baby, we don't know what could diss her
  Or it was only just a we roll
  That's why we be that way
  Until we are great and all
  Then he came
  I fell in love and everything changed
  A perfect teacher put in a frame
  Here's how our differences in things
  Will be the same, oh
  
  (Chorus)
  Girlfriend
  I thought you said you were my best friend
  So why ya tellin' all my business?
  Thought we were better
  But you show me where you stand
  Girlfriend
  I thought you said you were my best friend
  So why'd ya tell it to my boyfriend?
  I thought we were better than a fire or a man
  
  Time passed
  Feelings are bubbling like a wine glass(wine glass wine glass wine glass)
  My girl won't call me 'cause of my man
  Said we can't hang
  Because I checked out of the game
  But fix that
  She went and pulled them tricks out the hat
  And tried to tell 'em how I did act
  Whenever we go hangin' out back in the day ohh I
  
  Thought you'd be happy for me
  But instead you're spitting
  "Better be insulting"
  Oh yeah
  How could you put my business in the street?
  I found out what they meant
  By your best friend could be your worst enemy
  
  (Repeat Chorus)
  
  I thought you'd be happy for me
  But instead you're spitting
  "Better be insulting"
  How could you put my business in the street?
  I found out what they meant
  By your best friend could be your worst enemy ohhhhyeah
  Spoken
  "My girlfriend?"(My girlfriend.)
  "Why ya talkin' to my boyfriend?"(Ooh!He he he.)
  "I thought she was my best friend"(I thought we were tight.)
  "What you tellin' to my boyfriend?"(mmmhm We need to talk.)
  "Hey girlfriend."(Ah ha ha!)
  "Why ya talkin' to my boyfriend?"(Ooh!)
  "I really thought she was my best friend"(What happened?)
  "What you tellin' to my boyfriend?"
  Oh oh oh oh(Busted)
  
  (Repeat Chorus x2)
