The event, hosted by rapper and TV personality Nick Cannon, will additionally include performances by the Backstreet Boys, Colbie Caillat, Phillip Phillips, Toby Mac and Yolanda Adams. The event will also feature appearances by "Modern Family" stars Sarah Hyland, Nolan Gould and Aubrey Emmons-Anderson, Olympic gold medalist Gabrielle Douglas and actor Patrick Warburton. Mario Lopez will emcee from the Disney Resort, while Maria Menounos will serve as the parade's co-host.
This isn't Lady A's only chance to help fans celebrate the festive season. The trio released a holiday album, On This Winter's Night, earlier this year, which they say is a way to usher in their favorite time of the year.
"For me, Christmas Eve is definitely the best winter's night," bandmate Dave Haywood says. "Just that excitement ... of having all your family there. It's the perfect night in winter time."
The 29th Annual Disney Parks Christmas Day Parade will air on ABC at 10:00 AM on Christmas Day.
