According to TMZ, which spoke to sources with “direct knowledge” of the situation, Italy’s Minister of Culture reached out to Zuckerberg earlier this week, and both parties are apparently on board with the idea. “Some chance fight happens in Colosseum,” Musk tweeted early Friday morning.

TMZ reports that Zuck’s people passed on the invitation to UFC president Dana White, who in turn had his people contact the Minister. With both Zuckerberg and Musk evidently serious about this fight, the question at this point seems less of if it’s going to happen, but when and where.

However, it remains to be seen whether the fight will actually go down at the Colosseum. As TMZ points out, large events have not been held at the 2,000-year-old amphitheater in hundreds of years. The last time was in 2003, when Sir Paul McCartney performed inside the Colosseum for an exclusive charity show. But that was only for 400 people who paid up to $1,500 for a ticket.
