The singer recently dropped her second album, Too Young to Be Sad, which features hit track "feel like s--t."
"I was 16 so I feel like I was a completely different person,” Tate shared with Seacrest while reflecting on her breakout hit "you broke me first."
The singer will likely perform both during her Jingle Ball performance this weekend in Los Angeles and in NYC on December 10, alongside fellow Jingle Ball performers including Ed Sheeran and Dua Lipa.
"I just compare it to the last time I performed in New York two years ago it was in front of 150 people so it's super weird to see the comparisons," she shared. "... It's my biggest dream ever."
