Jamelia has urged Roxanne Pallett to "get help" following her accusations Ryan Thomas had punched her.
The 'Superstar' singer has, like the former 'Emmerdale' actress, been a victim of domestic violence in the past and accused the 35-year-old star of being the "perpetrator" in her row with her 'Celebrity Big Brother' co-star and said she'd found Roxanne's behaviour "triggering".
Appearing as a panellist on Chanel 5's 'Jeremy Vine' she told Roxanne - who was giving her first interview since quitting the house over the incident at the weekend - to find a way to deal with her emotions.
She said: "I have to say, it was triggering for me, I've been a victim of domestic violence and this might sound like a horrible thing to say, but in this instance, you were the perpetrator.
"I know your history, so it's difficult to see you in that role but you have to understand how that behaviour was triggering.
"The behaviour to Ryan and to discredit him, as much I understand your perspective and sensitivities - I react badly if someone shouts - but I saw what you did to him as an act of violence, I would like to you will get help to deal with these emotions, it was so heartbreaking to see the impact you had on Ryan."
And the 'Thank You' singer - who has daughters Teja, 17, and Tiani, 12, from past relationships, and eight-month-old True - admitted she made her older kids watch the incident and its fall out in order to learn how not to behave.
She said: "I made my daughters watch the episode because as awful as the situation was, it was an example of what not to do.
"Good can come of this situation, I admire and respect your honesty and its important you have apologised, just try to get help."
Roxanne admitted her past has made her more "sensitive" and she thinks the problem arose in the Big Brother house because she was surrounded by people who were unaware of how being a victim of abuse has left a long-term impact on her.
She said: "I don't think I realised how sensitive I was and because we're all used to the people around us taking it as normal, my family, friends, fiancé, my mum, they're used to how sensitive I am, but I was put into a situation where those people in the house didn't know what I've been through or my thoughts and feelings, they weren't prepared.
"Those people who rightly accused me of being dramatic and overreacting and discrediting Ryan, I agree 100 per cent...
"After it happened, I felt like, I don't know how to explain it, my mind ran away with me, I'm a sensitive person, everything in the house becomes so heightened, a look, a comment, an action, your insecurities, your sensitivities, the only thing I can explain it with is in the moment it felt worse than it was.
"I cant prove a feeling, I can't show you a feeling."
