Girls' Generation's Hyoyeon was apparently caught unaware in the middle of a midnight snack.

Staff members of�MBC's 'Dancing with the Stars 2' reported that they spotted Hyoyeon eating in the middle of the night during the show's June 28th recording.

This is especially surprising because of expectations that idol group members are constantly controlling their diets in order to maintain a slender figure. However, it seems that Hyoyeon has proved that a strict diet is not needed.

The Girls' Generation member has been constantly practicing and recording until early morning for 'Dancing With The Stars', which is probably why she burns enough calories to retain her idol image. To compensate for using so much of her energy, Hyoyeon is reported to have started eating midnight suppers now.

You can catch Hyoyeon's amazing dance skills on the upcoming episode of 'Dancing With The Stars 2', which airs on June 29th at 9:55PM KST.
