This is just my personal opinion so don't hate.
But if she doesn't release a new album this year it'll be a HUGE mistake. At least, a mistake in terms of sales and popularity.
Look at Gwen Stefani. Look at Fergie. They waited too long to release a new album that now they're having difficulty selling anything. They're comeback singles flopped.
So if P!nk waits another year to release something, it better be flawless. And it better be something different from her P!nk persona.
As a fan, I am disappointed because it looks like she is not working on anything.
But if she's doing what makes her happy, gaining weight, and taking much deserved time off then more power to her!
