If you happened to be walking around Manhattan early this evening and heard a deafening roar of coordinated, high-pitched screams, don't worry. That's just the noise that follows Nick Jonas and Hailee Steinfeld.
The singers/actors stopped by the famous Herald Square Macy's in New York City to announce the lineup for Z100's NYC Jingle Ball tour date, set for Dec. 11 at Madison Square Garden. On top of both Jonas and Steinfeld performing at the show, The Weeknd, Calvin Harris, Selena Gomez, Nick Jonas, Fifth Harmony, Zedd, Tove Lo, Charlie Puth, R City, Conrad Sewell and DNCE round out the lineup.

Z100 DJ MoBounce chatted with both Jonas and Steinfeld onstage about what it's like to perform in front of a huge audience.
"I didn't wear a diaper," said Jonas, when directly asked whether or not he used that particular protective measure in case his nerves got the best of him when he previously played the venue with the Jonas Brothers. MoBounce was very concerned about that detail.
Steinfeld, who will celebrating her 19th birthday at the show, says she has never even been to Madison Square Garden, let alone played it.
After staging a successful crossover with some girl named Taylor Swift as a mentor, she will have an unprecedented number of people screaming her name. This isn't the Academy Awards crowd.
The only major change from the previously announced Los Angeles date is that Demi Lovato will play instead of One Direction. Screams were especially loud for Vine-star-turned-pop-star Shawn Mendes and Australian pop punk boyband 5 Seconds of Summer.
After the big announcement, Nick Jonas sang his solo hits"Chains," "Jealous," and "Levels" for the crowd.
The New York show will be live streamed on Yahoo! and will air on the CW on Dec. 17.
The Jingle Ball tour also includes dates in Dallas, San Francisco/Oakland, Los Angeles, Minneapolis, Philadelphia, Boston, Washington D.C., Chicago, Miami/Ft. Lauderdale and Tampa.
