"Honest is the official autobiography from Tulisa, out on September 27 in hardback and ebook," publishers said.
"As the only official account of her story so far Tulisa is asking you for help in choosing the colours for her final book cover."
"Help choose my book cover for HONEST (out Sept)! We've got 3 to pick from - vote for your fave & order a signed copy," Contostavlos confirmed on Twitter.
Fans are given the options of turquoise, pink and dark blue to choose from.
The first 1,000 fans to pre-order the book in hardback from Amazon will receive a limited-edition signed copy.
In addition to her memoir, Contostavlos's deal with Headline Publishing also covers two novels.
