If so, are you familiar with the event? And if so, would you dare to bet on it?
I ask because almost no one has professional boxing knowledge, so it seems like it could only be considered "just another show".
I wouldn't dare place such a bet, and the reason for that has been said by yourself. None of them has professional boxing experience, it can go either way.
If the fight were to truly take place as it has happened many times elsewhere, where unprofessional people would challenge themselves to a duel, then either could win because they would both train well for it. Another danger in the bet is that physique doesn't matter. The less in look celebrity has won in my country in such a boxing challenge.
