“Every song on this album, unlike any of the other records that I’ve made, I’ve gone in and I’ve rewritten it over and over again until I felt like it was perfect,” the singer revealed on Jimmy Kimmel Live

Dua Lipa has been hard at work on her follow-up to Future Nostalgia and the singer told Jimmy Kimmel last night that she wrote nearly 100 songs for the LP. She also admitted to the late-night host that she penned all of the songs in a notebook she bought at CVS.

“Its got every single song I’ve written for this album,” Dua explained to Kimmel of the notebook, which she brought with her to Jimmy Kimmel Live. “I wrote 97 songs… And only because I have this [notebook]. It’s now become this relic of mine, in a way.”

She added, “I’m sweating right now at the idea of this book being lost.” Kimmel then wondered whether any of the 97 songs are “terrible,” which Dua confirmed that, yes, some are.

“Lots,” she said. “About like 80 of them. The second I write a song I know whether it’s good or not, or whether it’s close to being good and then I would rework it. Every song on this album, unlike any of the other records that I’ve made, I’ve gone in and I’ve rewritten it over and over again until I felt like it was perfect. Which I didn’t really have the confidence to do on my previous records. Like whatever I wrote on the day was pretty much what everyone heard and now this time around I’m much more confident in myself as a songwriter and as a performer and how I want things to be and sound and look.”

Dua Lipa’s new single, “Training Season,” is due out Feb. 15. The song, which she debuted during the Grammys last weekend, reflects on dating. She told Kimmel it is about “not wanting to train people up.”

“I think with every dating experience, whether it’s good or bad, each person leaves the situation having learned something,” she explained. “And they’ll be better for the next person.”
