South Korean singer PSY has rocked France with his hit tune, “Gangnam Style.”

PSY took part in the “Gangnam Style Flash Mob” at Trocadero Square in front of the Eiffel Tower in Paris on Monday. PSY performed his unique horse-riding dance with the crowd.

Participants of the event took pictures with their mobile phones and sang and danced to the chart-topping song.

The recent event was organized by a French music channel. The event’s organizers first estimated that some one-thousand people would show up for the flash mob but said that 20-thousand showed up.

PSY is set to wrap up his trip to France with a news conference and then visit Britain and Germany.
