Hagan's relationship with Cocozza was outed during an Xtra Factor segment last year when the singer remarked that he had "met her and banged her".
Commenting on the impact the relationship had on her view of men, Hagan said: "I would definitely pick normal guys over celebrity guys now. If you are with someone like Frankie, nothing is private in that world.
"You never know whether they are in it for money or to get press coverage. It's hard to trust people in the celebrity world."
Hagan famously rated Cocozza a 4 out 10 in the bedroom following their brief romance.
Speaking about her career outside of Geordie Shore, the MTV star claimed that she would prefer to try her hand at a show like Dancing on Ice rather than entering Celebrity Big Brother.
"I'd love to do Dancing On Ice. Or anything like that," she said.
"I just think Big Brother is like Geordie Shore, but you can't leave the house. You see people on TOWIE going on Big Brother, but when did you hear about Kirk Norcross recently? I mean even Frankie Cocozza has dropped off the scene.
"You don't even hear much of Amy Childs anymore. Is it the right thing to go on these shows? I don't need to go on Big Brother to show the real me, because we've already seen it on Geordie Shore."
Hagan also revealed to DS that she is still planning to further enhance her double-F boobs, commenting: "I want them a little bit bigger definitely.
"I had a boob job a long time before the show and now I've lost weight so now they're not how I want them. I want surgery to make them look better again and bring back some shape."
