Newcomer Halsey has exploded onto the music scene and she's dishing to ET about the surprising way she found out about her new album's breakout success.

"It's really crazy," she tells ETonline. "I fell asleep eating bagel chips the night my album came out -- there was no party, there was no champagne -- I woke up from a call from my manager [who] told me that the album debuted at No. 2 and I was half-asleep, like, 'What do you mean?!' What is two?' and he was like, 'Your album, Ashley! Your album!' and suddenly I woke up and was like, 'Oh my God!'"

"I was in my underwear, running around my house screaming," she confessed. "My neighbors underneath me are like banging on the ceiling telling me to shut up, it was so overwhelming."

Halsey's buzzed-about debut LP, Badlands, was released on Aug. 28 and hit the ground running at No. 2 on the iTunes chart, led by the infectious single, "New Americana." One week later, Badlands debuted at No. 2 on the Billboard 200 chart behind fellow newcomer The Weeknd. Now, these two powerhouses are gearing up to hit the road together, along with Travi$ Scott and Banks.

"I've been a fan of [The Weeknd] for years, so I'm really excited for this opportunity to go learn from him," Halsey said. "He's been so successful with pop radio this year, so I feel like I have a lot of notes to take."

The 20-year-old -- nee Ashley Frangipane -- says to expect "a lot of surprises in the set" when The Madness fall tour kicks off in November, along with "a lot of movie clips and props and stuff, and for me to jump into the crowd like a million times."

And, of course, a very special performance of her favorite track.

"My most favorite song right now is 'Colors,'" she said, "which is the big pop song on the album. It's so much fun [to perform]."
