This is really sad news, Nicole's one of the main monsters out there.
And to all people who feel triumphant because Lady Gaga just lost an important fan, just to let you know, when you're attached to one person for a long time, you'll never forget them, especially the things they have done for you. Nicole doesn't hate Gaga in any form, she's just not used to the new Gaga.
Lady Gaga is an active musician, she is not your typical mother****er in pop music that just drops a music and does not care about it. She's the type of musician who doesn't want to have a repetition of sound. She wants to keep moving forward and sad but true, Nicole cannot deal with that and so are a lot of people out there.
This does not cut Lady Gaga's career, she just started the era and there's a lot of chances to come soon. This does not also mean the fan base is breaking apart in any matter - we will still keep going without Nicole.
But Nicole, sis, if you're reading this right now, always now you're always welcome to come back again.
