Nicole tells a story about only being able to get into Wicked as a member of the audience. She also says that when she sang the song Popular in the bathroom, another person in the bathroom clapped. Laura Bell Bundy, who plays Nicole, was indeed in the Broadway show Wicked. She was the standby for the role of Glinda, which was originated by Kristin Chenoweth. So, she would have actually sung the song Popular on stage any time she was needed to fill in for Chenoweth. In an interview with Playbill.com, Laura Bell Bundy stated that she went on about 25 times while she was the standby for Kristin Chenoweth.
