In a video clip on Instagram, the 34-year-old singer and actress explains that she cannot disguise her voice.
Her voice is what it is, and she believes her craving for nicotine is the reason.
"If you're thinking about starting vaping, it's just not worth it. It's so stupid, and it changed my voice," she says in the clip, which appears to be aimed at people who don't like the way she sounds.
"If you don't like listening to my voice, that's completely understandable. I don't mind. Just don't listen," she says.
