On Tuesday, iHeartRadio shared clips from its upcoming iHeartRadio Holiday Special with PEOPLE — and they include performances by The Christmas Guy himself, Michael Bublé, and Kelly Clarkson! Beginning with Bublé, 46, the singer is joined by a band as he sings a rendition of the classic tune "Let It Snow," and later jams to the solo by his bass player. Meanwhile, Clarkson, 39, appears on a grand stage in a sparkly dress as she passionately belts out the vocals to her holiday song "Merry Christmas Baby," from her recent album, When Christmas Comes Around.

The show will also feature performances by Train and Pentatonix. Viewers can tune in to watch on iHeartRadio's YouTube or Facebook pages, along with the iHeartRadio app. Earlier this month, iHeartRadio rang in the Christmas season by converting its radio stations to all-holiday music through Christmas day. "Our listeners always anxiously await the day our stations flip to Christmas music," said Tom Poleman, Chief Programming Officer for iHeartMedia. "Kelly Clarkson, Michael Bublé, Train and Pentatonix have some of the best songs of the holiday season, and we're excited to have them perform on our show." Last week, the "Haven't Met You Yet" singer released a deluxe version of his hit album Christmas, in honor of its 10th anniversary. Bublé will also be the star in an all-new NBC Christmas special on Dec. 6 titled Michael Bublé's Christmas in the City. During the special, Bublé will head to Rockefeller Center's Studio 8H for a night of comedy, music and Christmas spirit with the help of some special guests.
