Hagan has flirted with Tindale throughout the MTV show's three series, but at the end of the most recent run, Tindale relented and slept with her.
The reality TV star, who famously had a fling with X Factor's Frankie Cocozza, revealed that her feelings had grown stronger for Tindale since the one night stand and in particular during filming of the summer specials Chaos In Cancun.
"In the past I wanted to bang him and stuff, but there was never really a friendship," said Hagan.
"But in Cancun, when we were there, you will see us develop a real friendship. It's not just about me wanting to bang him anymore. We actually care about each other and it develops over the five weeks. I think it will be interesting to watch.
"Obviously I still fancy him. But the most surprising thing is this new friendship."
Joking about Tindale's bedroom skills, she added: "I would give James a 9 out 10. There is always room for improvement. I can't give him a 10 because he'll get too much of a big head. But he is great though!"
