Plato Contostavlos told Now magazine that his daughter "only does it for the money" and can't wait to leave the show.
"Tulisa doesn't want to be there. She's bored of it. She doesn't need The X Factor, she's got N-Dubz," he said.
"I want her to leave X Factor. N-Dubz can do one gig and earn up to £500,000. I want her to make some serious dosh, millions, by doing an independent album with N-Dubz.
"What I want for her is security, so she never has to rely on anybody apart from herself."
It was recently reported that Sharon Osbourne has already been approached to replace Tulisa on the next series of The X Factor.
