Writing in her OK magazine column, the reality TV star - who has clashed with Price on numerous occasions - maintained that the 33-year-old should avoid dating.
"I'm glad she's single, she should stay that way for a while because keeping herself occupied will do her the world of good," Katona said. "As much as everyone slags Katie off, I can relate to her.
"She married Alex Reid on the rebound from Peter Andre like I married Mark Croft after Brian McFadden."
The mother-of-four continued: "She has this big persona saying how untouchable she is but I think she's really insecure and needs a man to love her. I used to be that way."
Meanwhile, Katona also hit back at press reports about her weight, after she was pictured on a night out with boyfriend Steve Alce.
"People should get over themselves, it's not like I've fallen off the wagon and shoving cocaine up my nose," she said. "I'm finally in a good relationship, I'm happy and content, so kiss my big fat arse!"
