After Timothée Chalamet showed up at his own celebrity lookalike contest, similar events have popped up in cities across and beyond the U.S. Here's a look at the winners — and what's behind the trend.

Since Timothée Chalamet turned up at his own contest in New York, other cities have been quick to hold copycat events, with hundreds turning up in London to find the best Harry Styles double. Lookalike contests have since been held for Dev Patel, Paul Mescal and Jeremy Allen White - although we’re curiously yet to see a female celebrity version.

Thursday’s Paul Mescal lookalike contest in Dublin was the first of many upcoming celebrity lookalike competitions to be held after the viral Timothée Chalamet contest in New York.
