New York, New York - Will the real Timothée Chalamet please stand up? Even the Hollywood star's most convincing doppelgangers, gathered in New York for a look-alike contest, did a double-take when the man himself swung by their festivities Sunday!

Around 20 young men, complete with chiseled jawlines and distinctive waves of walnut-colored hair, had gathered along with a massive crowd of spectators in New York's Washington Square Park, Variety reported.

The Call Me By Your Name star, hidden behind a mask and sporting a baseball cap, then crept up on the contest, posing for photographs with the competitors.

Images on social media captured the moment that Chalamet made his presence known, delighting the surrounding cell phone-holding fans.

"How do we know that that's really him? It could just be a very good look-alike," one user wrote in a comment.

YouTube creator AnthonyPo, who claimed to be behind the event and bears more than a passing resemblance to the star of Dune and Wonka himself, wrote on X, "thanks my number 1 fan (Timothée) for showing up."

At least one imitator was led away by police who apparently responded to the event because of the large crowd, which was forced to relocate.

The winner was presented with an oversize gold trophy and a check for $50, social media showed.
