She Tricked Me Again

I've been trying for months to get Bryn singing Beyonce's Halo on video but she always stops singing as soon as I bring out the camera.

The other day she kept singing when I told her I was going to get the camera, but being the strong-minded little girl she is (translation: she prefers to do the opposite of what I ask her) she switched gears when the camera came out and started singing her own words to part of the melody of Halo. I was trying hard not to laugh but lost it near the end...
