However, three years after being catapulted into the spotlight, Pattison, 34, left the series in 2014 after her engagement to Ricci Guarnaccio was called off during the fifth series.
Previously, Crosby revealed that they hadn’t spoken in six years after they both released fitness DVDs a year part, sparking a public rivalry despite being close on the show.
Then last year Pattison claimed that filming Geordie Shore’s drunken nights out had sparked her “toxic” relationship with alcohol.
Her comments have left many believing she won’t take part in the Geordie Shore: The Reunion series, which started on NOW TV last week.
Whether she makes an appearance or not, Crosby has confirmed their friendship is completely over.
She told The Sun: “If I saw her now, there would be no big bust-up, I’d smile and walk past.
“If she genuinely feels the show is something to be ashamed of, and that’s her experience on the show, which was unbeknownst to any of us, then so be it.
“If that’s her true feelings, that’s her true feelings. Who am I to say anything? It’s just that I had a completely different experience.
“It’s a dead weird one with me and Vicky, because it isn’t like we ever fell out – but when she left the show, she started making comments about us,” she continued.
“And it was just this never-spoken about feud. Don’t get us wrong, I wasn’t innocent – I did kind of gloat when my fitness DVD trebled the sales of hers.”
Following her stint on Geordie Shore, Pattison went on to win I’m A Celebrity in 2018 and has enjoyed stints on Loose Women, Celebrity Juice and Virtually Famous as well as hosting her own podcast, The Secret To….
The TV personality is engaged to Ercan Ramadan and plans to tie the knot in 2024. She recently shared her hopes to have a baby in the next five years and is set to start freezing her eggs next month.
Meanwhile, Crosby, 32, has also established a successful career both on and off the screen. She previously launched a clothing line for InTheStyle and has her own interiors online retailer, Naked Lane.
She also starred in her own reality series, The Charlotte Show and fronted MTV series Just Tattoo Of Us.
The TV star is now in a relationship with boyfriend Jake Ankers and is pregnant with their first child, a girl, due next month.
Geordie Shore: The Reunion Series continues on MTV on Tuesday at 10pm
