Andy Grammer and Lauren Alaina are among the performers set to celebrate the annual ball drop in New York City.

Pop singer-songwriter Andy Grammer and country artist Lauren Alaina are set to headline this year's Times Square New Year's Eve, the annual celebration featuring musical performers, confetti and New York City's famous pyrotechnic ball drop. 

Hosted for the sixth time by network TV host Allison Hagendorf and for the second time by Cake Wars host Jonathan Bennett, the show is available to watch commercial-free via a live stream that begins online Dec. 31 at 6 p.m. ET and ends at 12:15 a.m. ET. 

Headliner Grammer is scheduled to perform his hits “Honey, I'm Good,” “Good to Be Alive” and “Fresh Eyes” and to perform a song from his new album, The Good Parts, "Smoke Clears." Grammar will also be continuing the ninth-annual broadcast's tradition of singing John Lennon's "Imagine" minutes before the ball drops.

Alaina, meanwhile, will be performing her singles "Road Less Traveled" and "What Ifs," as well as Katy Perry's "Firework." Additional performers include L.A.-based dance troupe Kinjaz and the USO Show Troupe, which will be performing its hat tip to the armed forces, "A Military Salute."
