"Going on 'The Bachelor' was the most amazing opportunity I've ever had, but I did not have a fairy tale ending!" the 30-year-old told Us Weekly. "The girls hated me, my modeling career was destroyed and Ben and I had a tumultuous 11-month relationship that ultimately imploded. There are two sides to every story."
"I Didn't Come Here to Make Friends: Confessions of a Reality Show Villain," will deal with Robertson's experience while participating on the ABC series in 2011. During the season, Robertson was often portrayed as a bully as she was filmed calling some of the other girls names like "fatty" and "horsey."
"I wanted a chance to talk about what went down from my perspective, because I think there are a lot of misconceptions out there about me," she said.
In the end, Robertson received the last rose and became engaged to now-ex Ben Flajnik. The couple broke up in October 2012.
"Writing the book has been very cathartic -- I've definitely learned a lot about myself and love!" she said. "I think fans of the show are going to love it, it's totally juicy and hilarious."
"I Didn't Come Here to Make Friends: Confessions of a Reality Show Villain" will be released by HarperCollins Publishers.
