Pictures from the cast's St. Patrick's Day party, filmed on Sunday, 15 March, show the stars at each other's throats after an argument breaks out.
It's probably rather obvious why it's all so heated…
Diags has accused Tommy of cheating on girlfriend Georgia, saying that Tommy asked Diags to cover up for him during a night out in Newcastle last year.
As Diags' girlfriend, obviously Fran is on his side.
Georgia, meanwhile, has said she believes Tommy and is standing by her man. (Evidenced by these pictures from the party showing Georgia and Tommy kissing.)
Also making things heated is the fact Fran and Georgia have fallen out. We recently saw Georgia accusing Fran of stopping speaking to her for weeks. Georgia then called Fran "fake" for inviting Georgia to her anniversary drinks.
The Fran-Georgia fallout also affected Diags and Tommy, with Diags accusing Tommy of blanking his girlfriend.
Tommy has insisted nothing will affect his romance with Georgia, tweeting: "Nothing will ever break this bond.. My best friend my Girlfriend my Life #F**kAHater #PowerCouple. Love my @MissGeorgiakx more than anything.. People's opinions/ rumours mean nothing to us.. Night all."
Diags and Fran, meanwhile, haven't commented directly, but Fran has said Georgia is in denial.
