The Young singer, who is an X Factor judge, is angry at the criticism and is adamant she isn't going to "shut up".
She said on Twitter she is prepared to tackle her detractors - who include Simpson's outspoken ex-girlfriends Stephanie Ward, who is pregnant with his second child and mother to his 18-month-old daughter Skye, and Krystal Benjamin - head on.
Tulisa recently started dating Simpson, and earlier this year, the 24-year-old singer became the unwitting star of a sex tape which her ex-boyfriend Justin Edwards - also known as MC Ultra - released online.
Her series of tweets started with her saying: "They want me 2 shut up . be a lifeless robot that plays their shallow media games. be everything that's expected. a shadow of my former self . Not say what I think, feel or know, in the fear that they might destroy me 4 it. Any1 can write a twisted story, but it takes serious balls . To b this much in the public eye & scrutinised & still be myself. COMPLETELY!If u think u know me from what u read, u know nothin at all.
"So my message 4 the haters n the negative media is as 4 shuttin up. NEVER GUNA HAPPEN!!! that's what makes me tulisa! SO U CAN ALL BITE ME! (sic)
"N my message 4 my fans, supporters n ndubletts is . THANK U. U KEEP ME ALIVE! don't live a lie 4 any1 no matter they say, stay true 2 urself! #REALPEOPLE #REALLIFE #REALSTORIES (sic)"
