The reality TV star teased new relationships among the cast as she posed for her first topless photo shoot in Nuts magazine.
"The new series is amazing and we're all getting along really well - it's going to be like one big holiday," Hagan said.
"I mean there's always going to be ups and downs with us girls, but that means it'll be entertaining whatever happens.
"There's so much sex in this one! It's dirtier and more full-on but it's also more emotional too. Without giving too much away, there are going to be surprise relationships forming."
Asked who has the best boobs on the show, she added: "Sophie [Kasaei] has a really good pair. She always seems to just have her left boob hanging out when she's walking around."
On whether she would go on Big Brother, Hagan said: "I wouldn't say never, but I'd never leave Geordie Shore to go on it.
"I know some of the TOWIE lot have gone on it but I think they just do it to show that they have a realistic side."
Quizzed on whether she would have sex in the Big Brother house, she added: "Yes! I've already had sex on telly so it's not a big deal, is it?
"If I went on Big Brother and there was somebody in there who I fancied, I would."
