Hell hath no fury like Selena Gomez scorned.

Cameras caught the 'Stars Dance' singer berating paparazzi from the back of an SUV. While it's unclear what the particular paps did to set her off, whatever they did sure made her angry.

In the clip, Gomez sticks her beautiful, if angry and generously sized head out of the window and shouts, "Are you f---ing serious?!"

It may be worth it to note that it looks like a bodyguard is escorting someone away from her vehicle early on, and a related incident may have been what triggered her potty mouth and frustration.

It's safe to assume that whatever the paps said or did was pretty bad, as Gomez usually doesn't mind the spotlight (which may explain why she's still linked with Justin Bieber close to when her album drops).
