Okay, so where is the confirmation the weight issue was used to promote the single? You are very gullible letscauseascene1. I'm pretty sure she wasn't expecting to be called the names she was and plastered all over tabloids just so she can release a single. This was obviously already planned prior to the weight mess.
And Reeces, she performed / promoted the song on Ellen, The Early Show, GMA, and at several country events.

So yes, she
bothered. But you're right, a video should've been done to further that promotion.
