As Robin Thicke played his current hit ''Blurred Lines'' at this year's Taste of Chicago, the mayor kind of got into it!
Chicago Mayor Rahm Emanuel attended the show at the Petrillo Music Shell July 11. The R&B star played a set after Estelle.
Another concertgoer took a video of Emanuel enjoying the show and even dancing a little. Emanuel, a trained ballet dancer, even takes off his tie and puts it in his back pocket.
Emanuel previously danced on "Windy City LIVE" just after he was sworn in as mayor in May of 2011.
"When you're the mayor or famous or a public figure, you never know what camera is rolling on you at any given time," said Ryan Chiaverini, Windy City LIVE.
"I'm sure he has seen it. Somebody probably pulled him aside and said, 'I got to show you something," said WCL's Val Warner.
