It's one thing to be friendly with your ex, but to come across as full-blown BFFs is kinda weird, right?

While we wouldn't question Pink being there for her former husband, Carey Hart, to help him grieve over the recent loss of his younger brother, Anthony, Carey's fairly long cameo in the singer's new video for her tune "So What," does have us scratching our heads a bit.

After all, many of the video's visuals make direct reference to their defunct marriage, and at one point, Pink playfully puts her arms around Carey while she's belting out such lyrics as: "You weren't there/ You never were/ You want it all/ But that's not fair/ I gave you life/ I gave my all/ You weren't there/  You let me fall."

So take a look, have a listen and let us know what you think.
