Pop star Rita Ora, born in Kosovo, will join Seacrest in New York City for the first time.
"I was overseas, and this was always such like a million miles away... that wasn't real and then when you kind of get here you're thinking 'Wow! Everything goes into this show,'" said Ora.
"Dick Clark's New Year's Rockin' Eve" has been the most popular New Year's Eve countdown for over 50 years.
Even though Seacrest is one of Hollywood's busiest hosts and producers, he says "Dick Clark's New Year's Rockin' Eve" has a special meaning for him.
"He was someone who I admired and looked up to as a child, and someone I wanted to be. I wanted to be him when I grew-up so to have worked next to him during some challenging years for him and to take over or him has a special place in my heart," said Seacrest.
The heat generated by the million people in Times Square each year is the heart of the five-and-a-half-hour broadcast, but performers will be featured from around the world.
The show will feature comedians like Gabriel "Fluffy" Iglesias, Matt Friend, Ms. Pat and Sebastian Maniscalco.
Plus, Post Malone will perform from Las Vegas, NewJeans will be live in South Korea and Megan Thee Stallion will be rocking from New York City.
