Nadia Sawalha's sister Julia has blasted her sibling for "destroying" their family with "lies".
The "Loose Women" panellist opened up about her relationship with the "Absolutely Fabulous" actress this week, but Julia has now hit back on social media and accused the star of spreading "rubbish" on TV.
She tweeted: "So tired of #nadiasawalha talking about our "stormy" relationship which she created.
"I've kept my privacy for 6 years to protect my family, whilst she talks lies & rubbish. You have destroyed our family so don't sit on TV with your fake tears to gain sympathy & attention. (sic)"
She added that it's "very difficult" for people to judge when they just get "one side" of the story.
Julia, 50, wrote: "Yes well it's very difficult when you only see the story from one side. I'm not actually fighting, she is, but paints a very different picture publicly and I've had enough. (sic)"
Nadia, 54, opened up about her past as "Loose Women" marked 20 years on air, and while she heaped praise on Julia she insisted they've "always had a really volatile relationship".
Speaking on the show this week, she said: "She is totally amazing. She's really amazing my younger sister but we've always had a really volatile relationship.
"So we've always had periods of time in our life where we don't speak. I always say I have the best time or the worst time of my life with her. It's the same with both my sisters.
"My dad always says "formidable women". That's all he wanted. He came to this country with £50 in his pocket because he wanted six daughters who were free."
