Video may have cut away because he actually got it plucked, waxed, or lasered. Looks pretty real to me at the end.
Yea definitely fake, prolly put make up to cover his unibrow (u can see he only wiped the bottom) and being that he cut off the camera when he was "shaving".
Maybe I'm a sucker, but I think looked real and looked good. It's not like he removed a tatoo, he shaved his unibrow. It's easier than getting a haircut. And at this point he really doesn't need a unibrow to help make his brand distinct.
The way he brings the razor to his brow before the scene cuts, there's no way it would come out that clean. Not to mention, he's using the phone as his mirror. He drops it but says, "f**K it, not wasting time picking it back up so I can see what I'm doing".
