Lady Gaga's Met Gala stage fright? Or was she just f-bomb-ing with Anna Wintour

So why did Gaga refuse to walk the red carpet (it couldn't have been because she had nothing to wear) and  why did she refuse to come out of her room during the dinner?  According to the New York Post, friends tried to coax her out. So did Warner Music execs. Finally Oprah Winfrey persuaded her to come out.
