He doesn't seem like the kind of guy who would let anyone get away with calling him "cute."
The Daily Mail reports the footage is of the 29-year-old multimillionaire at age seven. He's apparently at a wedding ceremony and, let's admit it, having a good time.
Weirdly, much of the McGregor which fans either love or hate today—the Notorious One doesn't inspire neutrality—is on display. The sharp (if out-sized) suit, the excellent footwork, and hamming it up for the camera.
As UFC is about theater as much as it is about fighting, we wouldn't be surprised if a future McGregor opponent figured out a way to taunt the champ with this video.
Even though we have to admit that yeah, it's pretty adorable.
