The Price matriarch then kicks Karl out of the pub in public view, calling him a "pathetic, lying scumbag", according to Collins.
Speaking to Soaplife, the actress argued that Karl is Stella's "weakness".
"I'm not sure that she can [leave Karl]. She seems strong on the outside, but Karl is her weakness," Collins admitted. "I think she loves him more than she actually knows herself. Like a lot of strong women, there is always someone in the background and they're often very different to their partner."
