Whether it makes any difference or not is an open question, but many people feel Eminem lip-synced his performance on Saturday Night Live this weekend.
While the critics generally loved Kerry Washington on SNL, Eminem received mixed reviews after taking the stage to perform his new hit single "Berzerk."
No one's likening the "Rap God" to Milli Vanilli, who couldn't sing in the studio either, or to Britney Spears (you gotta hear her actual vocals), but still.
Take a look below and see if you think it's as obvious as we think:
At times, when the rapper pulled the mic away from his mouth, it sure sounded and looked like the vocals continued at full volume. Even so ... does it matter?
People's view of lip-syncing seems to vary on a case-by-case basis.
Some stars get torn apart for it, others don't. If it's the Super Bowl, people TWEAK. Other times, less so. Similarly, some mask it better than others.
You tell us: Was Eminem lip-syncing on SNL, and does it matter?
