When interviewed by UK’s News of the World about her divorce, her experiences as a single woman and her getting back with ex-husband Carey Hart, Pink says:

“I’m not embarrassed about being bisexual. This is who I am. Love is pure and I try to keep it that way. This is who I am, what I feel. I think it’s unnecessary to draw the subject out, but I think it even more stupid not to discuss it. It seems as if bisexuality is a trend and I should whip up the masses. Well, I don’t believe in trends, I just believe in me.”

All that tells me is that women weren’t enough to keep her from men her ex.
