Cheryl Cole, Nicola Roberts, Tulisa Contostavlos and Holly Willoughby were all criticised by the former glamour model in her one-off publication.
On Cole's X Factor USA outfit, she wrote: "The whole thing is absolutely hideous.
"I don't know who's responsible for the outfit and the horrific hair but I hope Cheryl sacked them. It looks like she's put on weight."
Regarding Cole's Girls Aloud bandmate Roberts, Price continued: "She always gets it wrong. She is trying to be unique but she doesn't have the confidence to carry it off."
Meanwhile, the reality TV star said of new X Factor judge and N-Dubz star Contostavlos: "From what I know of Tulisa's style, I much preferred how she used to look, you know, a bit more street."
The 33-year-old also slammed This Morning host Willoughby for allegedly looking "mumsy", adding: "You don't ever see her looking really sexy, do you?"
