The former glamour model said that she does not like being compared to Price, claiming that she is happy to have moved out of the limelight for a career as a tattoo artist.
"Does anyone care about her anymore? I don't," Marsh told the Daily Star. "Look, Kate would sell her own grandmother to a magazine if she could - I wouldn't.
"Good luck to her but I wouldn't do it. That's why I'm tattooing now. I'm keeping it real. I don't envy her life."
The Celebrity Big Brother contestant also took a swipe at new ITV2 show The Only Way Is Essex, claiming that the reality series is a poor portrayal of her county.
"It's embarrassing for Essex people and shows the worst side of them," she said. "It makes me feel sick. They all love themselves, they're obsessed with designer labels, all they care about is what they look like. Real Essex locals are hard-working, salt-of-the-earth people.
"This show is all people whingeing about their love lives and showing off all their money. There's so much more to me than that."
