The model, 21, has kept a dignified silence since their relationship appeared to fizzle out weeks after returning from the jungle.
But now, she has told the The Sun (via The Mirror) that she ended her relationship with the TOWIE star to avoid becoming "the next Katie Price and Peter Andre".
She said: "I want a real, normal relationship where everything happens naturally and you are just allowed to be."
She went on to say: "I still fancy him, but I don't want to be the next Katie Price and Peter Andre."
The pair became close on I'm A Celebrity at the end of last year and their friendship blossomed into romance after they were both voted out on the same night.
Katie and Peter also met on the reality show in 2004 and went on to get married and have two children, living their lives in the glare of the spotlight - something Amy clearly wanted to avoid.
Although Amy admits she had real feelings for Joey, she reveals "everything started to fall apart" when they returned to London and pressure was put on them.
She added: "It felt like if we were going to be together, we had to be committed to the relationship, because we'd be presented to the world as the Joey and Amy show."
