“& Juliet. We don’t need no stinkin' Romeo.@broadwayinchicago,” Squerciati wrote in her caption. “Also I barely made it from work! We slapped on the wigs in the elevator, I ate my dinner on the El Platform, and we had to sprint a few blocks! (Just wanted to give you the reality behind the IG photos 🫠.)”
