The N-Dubz star, who sits on the panel of Britain's The X Factor, has agreed a contract with chiefs at Headline Publishing Group, who will release all three books.
Contostavlos says: "I'm really excited to start work on these books. Having my novels published is a dream come true for me.
"I'm also looking forward to sharing my life story so far; I've got lots to tell. Headline is the perfect place for me to build my writing career."
Headline's Deputy Publishing Director, Sarah Emsley, adds: "Aged only 23 she has battled through a tough childhood and difficult personal relationships whilst acting as the sole carer for her mother, to become an incredibly successful recording artist...
"Tulisa's story has incredible breadth and depth for someone so young, and we are absolutely thrilled that she has chosen Headline to be her publisher."
The singer's memoir will be released later this year, while her novels are expected to be put on sale in 2013 and 2014.
