Things have been tense between the girls after Vicky made comments about Marnie's relationship with Ricky Rayment on two occasions in a magazine column.
And after reading Vicky had joked about the pair's engagement and baby plans, both Marnie and Ricky couldn't stop themselves from hitting out at the 27-year-old on Twitter.
Vicky had taunted the pair, telling them they "aren't the Beckhams" after learning Marnie's plans to name her child with Ricky, London.
Her comments hit a nerve with former TOWIE star Ricky who was quick to tweet Vicky to tell her she was "obsessed". He said: "Stop talking about us please. Every single week it's something new. Go away. #obsessed."
Marnie, meanwhile, hit back: "Wow she's talking about us again... BORE OFF AND LEAVE US THE F*** ALONE #troublemaker."
She later added: "If people constantly want to talk about you and put you down it obviously means [you're] doing something right... PURE JEALOUSY."
Vicky (who is currently holidaying in Ibiza with new boyfriend Stephen Bear) is yet to respond.
Marnie's tweets towards Vicky come as she recently announced she has left Geordie Shore.
As reports surfaced hinting Marnie's exit from the show, the starlet took to Twitter to confirm her departure, telling fans her fiancé Ricky comes first.
"I couldn't continue in the show in a relationship. It wasn't fun to me anymore and I didn't enjoy it," she said. "Picking between my future was extremely easy, Ricky would always come first.
"I chose to get engaged to Ricky and say goodbye to the show - a decision I am extremely happy with."
Ricky had popped the question to Marnie while she was filming series eleven of Geordie Shore in Greece at the end of June. His proposal came six months into the pair's whirlwind romance.
