[Video] SNSD is filming another new CF ,Tae Yeon is not seen during the interview!

The girls of SNSD were interviewed when they were filming for a new CF.

I got no idea what CF they are filming for but i am confident that it is related to food,that's what i can tell.Great to see them in the kitchen again but Tae Yeon is not seen during the interview.

Reason?Most probably practicing for musical!
