Britney Spear's greatest comeback could be a great comeback because when artists has not put out an album in a while or have not been seen in the spotlight their potentials could be to do their very best than before. i personally feel that Britney's comeback could her gaining fans as well being the greatest because while she has not been seen in the spotlight she most likely has been working very hard.
No, this will not be Britney Spears' greatest comeback yet, because she is too old to be relevant anymore. People did not like Britney because she was a particularly good singer. People liked Britney because she was popular and because she was a good dancer. She is past her prime and should do something else.
