Lady Gaga WISH she could ever sing like Christina. Christina should be compared to the great vocalists like Whitney but not Lady Gaga or Britney. Lady Gaga is an ARTIST/ENTERTAINER/FASHION ICON. Britney is a ENTERTAINER/DANCER. These comparisons need to stop. Christina is a true VOCALIST. Britney is not a vocalist. Lady Gaga is not a vocalist. Christina will never be like Whitney who she looks up to, but Christina is definitely one of the best vocalists of this generation. She just happens to be a great vocalist who likes to experiment with different styles, fashion, etc.
