Frankie Gaff raged at Tina Stinnes on tonight's Made In Chelsea.
Christiane 'Tina' Stinnes first appeared on the E4 series very briefly back in 2014 but made a dramatic comeback tonight.
Tina - who last year appeared on ITV2's Love Island - returned amid rumours she and Jamie Laing had got together behind Frankie's back.
Jamie and Frankie's relationship was left hanging in the balance last week after it was revealed both had cheated on one another.
Jamie admitted to getting 'inappropriate' with Tina over Christmas, a confession made even worse for Frankie given her and Tina's rivalry.
Tonight, Frankie an Tina came face to face following more rumours of Jamie's flirtation with the former Love Island contestant.
Frankie started bluntly: "Why the f**k are you here? I think you're disgusting."
She continued: "Why are the f**k are you getting in a car with him, being all over him?"
Tina defended herself and hit back: "Have an issue with him, don't have an issue with me... I have done nothing wrong."
But Frankie snapped, branding Tina a "f**king sl*t".
"Why are you so rude?!" reacted Tina before walking away.
The developing Jamie-Frankie-Tina love triangle wasn't the only source of relationship drama tonight.
Harry planned a raucous country party where he intended to charm ex Ella back, behind Julius' back.
Meanwhile, Fredrik heard about Olivia's recent dalliances and asked Mimi out on a date.
Made In Chelsea airs Monday nights at 9PM on E4.
