Dua Lipa quit smoking ahead of her mammoth world tour as part of an effort to improve her vocal performance.
The singer, whose hits include Don't Start Now, announced that she had made some lifestyle changes as the 81-date-long world tour continues this year.
Dua completed the final date of the tour's UK leg last night, explaining how she had recently suffered with a bout of laryngitis.
She told the Sun: "I had laryngitis in December and that kind of kickstarted me quitting smoking a month earlier than I was supposed to. But I did it and I have stuck to it.
"I have this habit tracker on my phone where every night I tick off all the good things I have done for my body and things I have done for myself."
Nonetheless, Dua has now said that she feels "invincible" onstage after changing some of her health and fitness practices to keep in shape for the demanding tour.
These have included splashing out on a personal yoga instructor to accompany her whilst goes on the tour.
During the latest episode of her At Your Service podcast, she said: "I feel like when I get up on stage there is a different kind of confidence and, you know, I feel very invincible at times when I am performing."
Dua added: "I feel so excited and there is a lot of adrenaline - and sometimes I don't feel confident at all.
"There are moments when I am on stage every night and, yeah I am quite exposed, and I am dancing and performing and I feel like I have to work out and stay really healthy in order to feel good about myself.
"So I only like to do things that make me feel good and that also helps with my confidence."
The singer recently drew attention in February of this year when she split with her long time management firm just nine days into the world tour.
The 26-year-old star terminated her contract with Ben Mawson and Ed Millet's TaP Management, and it is not currently confirmed if she is speaking with new management companies.
Dua's massive tour includes 28 stops across the US, and is due to finish in Perth in Australia this November.
In December Dua also split with her boyfriend Anwar Hadid as the pair had been struggling to keep the relationship going due to their conflicting work schedules.
After releasing her last album in 2020, the singer has now confirmed that she is currently working on some new material.
"I've done a big chunk of writing: It's starting to take shape; I've got a lot of it recorded", she said.
"It has a vision. It has a name, I think - for now. It's just been fun experimenting. I'm always going to make pop music, but it has its own unique sound, which is exciting and something that feels like a movement from 'Future Nostalgia," she added.
"It's still in baby form, so we'll see as it progresses. In all honesty, it's probably not what my fans want to hear, but I'm in no rush."
