The Britain’s Got Talent star was told to stay calm and still as she performed her song Who I Was Born To Be – which is supposed to be a ballad – while recording her forthcoming TV special (which will be aired this Sunday on ITV1).

But instead, halfway through the song, she started to throw her arms around and jig franticly across the stage in front of a surprised audience.

Miffed producers then asked SuBo to do the song again, this time sans crazy dance routine. They then resumed filming, but then Susan broke into dance for a second time. A show insider commented.

“It was odd and very out of character with the song and with the show.

“Susan just looked like she was doing it as a break from the seriousness and the pressure of having to sing throughout a show. It’s going to give us a bit of a headache – we will have to edit around it.”

Anyway, it seems as though Susan has developed a bit of a penchant for doing this; earlier today we bumped into the singer doing much of the same (you know – jigging about and pulling funny faces) while appearing on a French TV show.
