New mom Katy will deliver a rendition of the classic I’ll Be Home for Christmas along with her original holiday tune, Cozy Little Christmas, during the event on November 30th.
She’s the only star on the line-up to perform their own original composition, with K-pop sensations BTS covering Santa Claus Is Coming To Town and Pink belting out The Christmas Song (Chestnuts Roasting on an Open Fire).
Also appearing is Andrea Bocelli, Michael Buble, Chloe x Halle, Derek Hough, and Hayley Erbert, Julianne Hough, Adam Lambert, Leslie Odom, Jr., and Kerry Washington.
The event will also host Disney on Broadway as it returns to the New Amsterdam Theatre, where the casts of The Lion King, Aladdin, and North American touring companies of Frozen will team up for a performance of Let It Go.
The one-hour event will include animated on-screen lyrics for viewers to sing along to and the special will raise awareness about Disney’s Feed the Love campaign.
Tune in from 8 pm ET on ABC.
