People that are fueling her new attitude are not going to do anything for her career
Just like not reigning in Gaga's egotism
Just like not reigning in Britney's party habits/lifestyle before her break down
The same people tearing her down now are the same people who were doing it before. Haters will be haters. Not saying i agree with what's she doing is necessary.
Still no real confirmation from either parties, really. All personal feelings about Chris Brown aside, I will say this: If the rumors are true, "Birthday Cake" will have the biggest single sales week of the digital era. It may fall like a rock after that, but the curiosity of such a collaboration would break single week records.
