Her reason for departing was the toll being in the band had taken on her mental health.
This week, Nelson confirmed she had not spoken to former band mates Leigh-Anne Pinnock, Jade Thirlwall and Perrie Edwards.
“I haven’t spoken to the girls,” she told Glamour. “It is weird because for so many years we were as close as sisters, together every hour of the day for weeks, sharing beds, laughing, crying just 24/7 the four of us together and then… Nothing.”
“Hopefully at some point in the future we can all come back together. I love them. They are my sisters in so many ways, but for the time being we just don’t talk,” Nelson added.
Nelson’s struggles during her time with Little Mix are no secret after she opened up about them during her 2019 BBC documentary Odd One Out where she revealed abuse on social media got so bad she attempted to take her own life.
Nelson signed her solo deal with Polydor Records and her song is already climbing the charts.
She said of the new music: “I just want to be myself and be real. I want my fans to hear that they’re my stories because they genuinely are. No-one has come in and told me what to write about. This is the music I’ve always wanted to make.”
