The popstar is currently filming the new series of The X Factor, due to air its premiere next Saturday (August 18).
According to 4Music, Tulisa told The Times that if she hadn't risen to fame with N-Dubz, she'd "be living with a drug dealer in a council flat".
She added: "I can imagine having a baby because there's nothing else to do."
She also revealed in the interview her friends' unusual nickname for her: "One of my nicknames is 'the beautiful pig'. Eyes bigger than my belly, massive portions. I could probably sit here for like, three hours going through one meal and I won't finish until it's all done.
"The only time I'm a diva is with my food. I hate sharing. I'd rather go into the kitchen and make someone a whole new meal than give them some off my plate."
Tulisa is set to release her autobiography 'Honest' in September, with new single 'Live It Up' also released on September 9.
