The context: Two years after they got married, Pink and Carey announced their split in 2008. She wrote the song as an anthem of empowerment; after the trauma of a breakup, she was letting the world know that she was still a badass. It's just one of many songs inspired by Carey off Pink's Funhouse album.
In her words: Pink convinced Carey to star in the video, but he had no idea what the song was about. He found out on the set that the lyrics were all about their relationship: "He hadn't heard the song before he showed up for the video. He's a good sport, he knows how psychotic I am, he spent six and a half years with me. A year with me is like dog years." Pink also admitted that the personal lyrics started out as a joke, but they kept going and it just kept getting "wronger."
Most revealing lyrics: "I guess I just lost my husband / I don't know where he went / So I'm gonna drink my money / I'm not gonna pay his rent."
