Jesy Nelson has signed a solo deal with global management firm YMU.
The 29-year-old announced in December that she was leaving Little Mix due to mental health reasons and she has now released a statement about her "next chapter."
"I am so excited to join YMU and can't wait to start my next chapter," she said in a statement.
YMU's clients already include Take That, Steve Aoki, Ant and Dec, and Fearne Cotton.
Mary Bekhait, group CEO of YMU, said: "Jesy has enjoyed incredible success as a recording artist and performer and is well placed to further her remarkable career.
"She is a hugely talented, versatile and authentic artist with a strong creative vision, and we are looking forward to helping her realise that."
Nelson hinted she was set to release solo music last month when she posted a selfie on Instagram with the caption, "Let's go" along with some musical emojis.
She further fuelled speculation that she's working on new material by sharing a studio snap of herself alongside songwriters Patrick Patrikios and Hanni Ibrahim, who both worked with Little Mix previously.
Nelson's former Little Mix band-mate Leigh-Anne Pinnock also signed a solo deal with a PR agency earlier this month, while saying she is still committed to the group.
"This is such an incredibly exciting time for me and my career," Pinnock tweeted.
"Can't wait to show everyone what I’ve got coming up. I will continue to work on my solo endeavours alongside my Little Mix commitments."
