Pattison, who embarked on an on-off relationship with Jay Gardner in series one, added: "You know I like to have a little tash on! There's plenty of that!
"It's completely outrageous and ridiculous. Everything that happened in the first series we've done it again but we've done it times ten.
"There's make-ups, there's break-ups, there's disagreements, there's banging, there's tashing on, there's drinks. Its just craziness, it's just Geordie Shore!"
Geordie Shore returns with new additions Ricci Guarnaccio and Rebecca Walker on January 31 at 9pm on MTV.
