Well this is certainly a strange date night!
How do we know?
You'd think they wanted to dance to the music together!
Ch-ch-check out their videos (below)!!!!
Even though we have definitive proof that Britney Spears is lip-syncing during her residency performances in Las Vegas, front-of-house sound engingeer Robert "Cubby" Colby pinky promises that she is singing live.
"Britney sings every song live, but there are additional tracks when they're doing the heavy dance numbers. Snapshots give Marc the security of knowing that these levels that they work on so hard translate to the live environment."
It's just plain silly to fib when you then go on to confirm there might be some lip-syncing.
We're not saying we mind that she's too busy shaking it to sing, but we don't appreciate his attempt to fool us.
