Barton featured in a recent episode of ITV2 series Fearne and..., but told OK magazine that the episode left her upset.
"I can't hear Fearne's name without seeing red," she said. "I cried my eyes out when I first saw it.
"I wish I hadn't done it and that's bad because there are enough misconceptions about me in the press. She's got nothing to lose if she makes a more salacious story, she's only got everything to gain.
"I just find her messed up, to be honest."
Barton also spoke about one particular scene in which Cotton was shown waiting outside her home.
"Fearne never let on that she was irritated about waiting," she said. "She acts like everything's so great and she loves you and they cut it together and make it seem like it was a terribly painful experience for them."
She added: "I don't want to start a feud with her, it's not worth it to me. She likes the fame, it doesn't affect her like it affects the people she's documenting."
