The clip finds the 25-year-old dancer tearing up as she opens up about her first time in the famous theatre.
"After the 'first' show at the Beacon theatre in NYC," Hough captioned the video. "'First' time performing on Broadway... Thank you so much to our 'first' audience! You guys rule! #moveliveontour"
Hough and her brother Derek Hough starred in two performances of their Move Live Tour on June 21 on Broadway. The show, an interactive performance in which attendees are expected to dance along, kicked off on May 25 and is set to travel across the United States.
The siblings opened up about their set to People magazine in early June, saying the tour had brought them closed together.
