The couple - who knew each other when they were teenagers - began dating earlier this year. However, in an interview Foden confirmed that he had ended his relationship with Katona.
"It just seemed really forced. All the people there were connected to her management and they were filming everything," he told Reveal magazine. "I just couldn't be doing with it.
"The TV crew were trying to get people doing things. I just hung around in the background before sneaking inside to watch the football."
He continued: "They asked me if I'd do an interview for Kerry's show but I said no. Then they started talking about a photoshoot for a magazine. I'd already told them I wasn't interested in anything like that, but they just wouldn't let it rest. I was uncomfortable.
"Kerry's world is just too mad. She's a lovely girl but I can't live in that showbiz bubble. The people around her are friends, but they are not real friends, if you know what I mean."
Foden, who appeared on the latest series of ITV1 dating show Take Me Out, added: "They are there because they share the same management. I feel really sorry for Kerry. She's a great girl but I honestly think she's really lonely and homesick."
The 27-year-old claimed that he had refused to sign an agreement not to discuss his relationship with the reality TV star.
Katona had previously admitted that she thought Foden was "way out of my league".
