Jessie Wallace is said to be 'at war' with her sister which is worse than any EastEnders storyline.
The actress, who plays Kat Slater in the soap, has been fighting with her sister Danielle Mason for the last seven months.
Danielle, 36, said her sister, 48, "stitched her up" and they haven't spoken since March.
The glamour model told the Daily Star Sunday: “We’ve fallen out again. She stitched me up on my birthday, so I got the hump. I just got the nark. We fell out.
“We had a massive row and called each other all the names under the sun. It was worse than anything on a soap opera.
“She is quite grown up. She doesn’t argue back. But I am horrible.”
They have fallen out in the past and were at loggerheads for an entire decade.
Jessie was accused of ignoring her stepfather Ron Mason while he battled leukaemia.
It was claimed that she only texted her mum Anette twice during the whole ordeal.
Danielle now believes she'll always have a rocky relationship with her sister.
She added: "We are sisters so we just row about sisterly things. We’re like any normal family. We fall out.
"She’s grown up a lot but I haven’t. That’s just the way we are."
Danielle continued: "I want to say we’re similar, but we aren't.
"She does her acting thing, I do my thing… but she doesn't like the limelight."
Mirror Online has contacted Jessie's reps for comment.
