Kelly Killoren Bensimon goes backstage to chat about Kanye and music with Austin Mahone: Holiday season fever is already here, and with that comes many a teenager’s favorite event: the Z100 Jingle Ball on Dec. 13. And this year’s lineup is filled with stars, including Miley Cyrus, Robin Thicke, Pitbull, Enrique Iglesias, Fall Out Boy, Macklemore & Ryan Lewis and Selena Gomez. This season’s breakout star, Austin Mahone, will also be performing. The official charity partner for Z100’s Jingle Ball 2013 is the Ryan Seacrest Foundation, which is dedicated to inspiring today’s youth through entertainment and education-focused initiatives. The nonprofit will receive $1 from each ticket sold. In 2011, Mahone became a YouTube sensation and even opened for Taylor Swift’s “RED” tour. Mahone — who was feeling ill and hospitalized Thursday according to his rep — spoke to me at the lineup announcement last week at Aeropostale in Times Square, Mahone dished with me while my youngest daughter and her best friend sat by in awe of the 17-year-old star.
