New Year's Rockin' Eve co-host says BTS performance will be 'insanity'

Before Lucy Hale rings in 2020 alongside her longtime friend and now "New Year's Rockin' Eve" co-host Ryan Seacrest, the actress said she's prepared for anything and revealed the performance she's most looking forward to seeing live in Times Square.

"Nothing will put a damper on tonight, bring on whatever, I'm ready," Hale told "Good Morning America" about the "full circle" opportunity to be hosting the holiday in New York City.

"I didn't think they were serious at first," she said when she first got the call from producers. "This is the only show I remember watching -- it was just on my bucket list to come to New York -- not to be actually hosting -- so this is a very full circle surreal moment for me. And I've known Ryan for like 16 years, so I'm very lucky."

Hale, 30, who previously co-hosted the evening of revelry from New Orleans, said that despite the many rehearsals, the great thing about live TV is "that things just change."

"You sort of have to be on your toes and expect anything," she said. "I'm gonna have a lot of feet warmers and a lot of coffee, it's a long day."

The "Pretty Little Liars" star said she's excited about Alanis Morrisette, who will be performing just down the street, "but I'll definitely be able to hear her."

"We have Sam Hunt, Post Malone, BTS -- which is going to be insanity," she said. "I don't even know what to expect. I feel like they would draw a million people alone," Hale said of the K-Pop boy band.

As for her thoughts going into the New Year, Hale said she has a resolution to declutter different aspects of her life, thanks to a conversation with Seacrest.

"Ryan and I were talking yesterday and kept saying organize our life, declutter," she said. "I kept thinking of all the stuff I have that I don't need -- Marie Kondo, I need to do that to a lot of areas of my life."
