The "Break Up Song" hitmaker appeared on U.K. TV show "Richard & Judy: Keep Reading and Carry On", where she spoke about some of the books that have had an impact on her.
During the discussion, she explained that "Why I'm No Longer Talking to White People About Race" by Reni Eddo-Lodge helped her come to terms with her feelings, telling the hosts, "The book inspired me because in the past where I have felt invisible, overlooked, especially being the darkest member of the band that I'm in, Little Mix."
"I think I was going through some things and I was struggling a little bit and not really understanding why I felt the way I did. Then I read this book and it really, really helped me."
Another book the "Wings" star mentioned that had an impact on her was "The Skin I'm In" by Sharon G. Flake as she shared, "This is all about a younger girl who gets bullied for having darker skin and learning to love the skin she's in."
"Such an important message, especially for young girls. I would also really recommend that book."
The star's comments come after it was announced she is set to front a BBC Three documentary about her and others' experiences of racism and colourism - following on from fellow Little Mix singer Jesy Nelson's "Odd One Out" programme, which was acclaimed for highlighting the effects of online trolling.
An air date for the new documentary has yet to be confirmed.
