The lip-sync deal is unfortunate, but if anything it added hype to her Superbowl performance.
I was more hurt by the surrogate rumors(that are still being talked about today), but as everyone sees, it did not affect her career at all.
Controversy sales. It was a controversial moment that will now bring more awareness to Beyonce. Pepsi is aware, so I'm sure they are glad that the attention is on her, more than ANY other pop star at the moment.
