Beyoncé’s lip-sync controversy: Why celebrities do it

Beyoncé’s lip-syncs.

Here’s a shocker: Whitney Houston’s historic rendition of  “The Star Spangled Banner” during the 1991 Super Bowl was also lip-synced!

“The music was pre-recorded, and so was the vocal,” Houston’s musical director Rickey Minor, revealed last February.

So why do professional singers lip-sync the national anthem? According to voice coaches, there are several good reasons not to sing the “Star Spangled Banner” live.
