The soap star and lads' magazine favourite confirmed that she had packed three items of swimwear for her upcoming stint on the reality show.
"I went shopping in London before I flew out to buy some bikinis for the jungle," said Flanagan.
"You can take three sets in and so I am going to do that.
"I don't mind that it is going back to basics because I will make sure I am tanned, manicured and I have got my lashes on!"
The ex-Coronation Street actress, 22, also confessed that her biggest fears were heights and spiders. "I am fearful of heights. I have never jumped out of a plane and I don't even like rooms high up in a hotel." she said.
"I will scream if I see a spider at home but we will all be in the camp together and we will all deal with it."
Speaking about her current boyfriend, footballer Scott Sinclair, she added: "We have just moved into a new house and I am going to miss him so much. Again, I am just trying to not think about everything too much."
