[3] In December, speaking about the song, she referred to the need to "have your own creativity and place" away from others and how those other voices and opinions can lead to a feeling of frustration: "At the end of the day you're like 'Ahhh!

In their review of the song, Billboard noted that it was a "fun little romp, but ['Outta My Head'] may have difficulty returning Simpson to top 40 favor".

Simpson tries to escape from this scene, fighting off interviewers and cameramen, but is captured by doctors from a mental institution and taken away in an ambulance.

In her room, Simpson, now in a straitjacket, finds herself again surrounded by interviewers and cameramen; this time she bounces off the walls and spins around in the air as the video ends.
