Milli Vanilli 'Singer' Fab Morvan -- So WHAT If Beyonce Lip-Synced???


didn't do ANYTHING wrong by lip-syncing her way through the national anthem at the Presidential Inauguration -- so says one of the most famous lip-syncers of all time ... Fab Morvan from Milli Vanilli.

Fab tells us, "It's hard to believe, in this day of auto-tune, that people are still acting surprised [by Beyonce lip-syncing.]"

He adds, "Everyone knows Beyonce can sing. Everyone should just step back and relax. There are far more important things to worry about. But I can certainly relate to what she's going through."

You can say that again -- but we still gotta ask ...
