TV watchdog Ofcom is to investigate Coleen Nolan and Kim Woodburn's Loose Women row.
The two TV stars were brought face to face on Loose Women last month in a bid to end their 'feud'.
They had previously clashed repeatedly last year when both took part in Celebrity Big Brother.
And there was no end to their bad blood this week, as instead their attempts to to sort out their differences ended in it all kicking off between the pair live on TV.
Kim ended up storming off the show, as viewers accused Coleen, sister Linda and their co-hosts of 'ganging up' on her.
The scenes have prompted a total of 7,900 complaints to TV watchdog Ofcom.
Ofcom's spokesperson this week said it was investigating whether the show "fell short of generally accepted standards."
In a statement at the time of airing, a rep for Kim said: "Kim was invited onto Loose Women as she was told Coleen wanted to hold peace talks with her. When she arrived this morning, Kim was briefed and told Coleen would speak first and give her reasons for their row. She was told Coleen wanted to bury the hatchet.
"However when Kim walked on set, Coleen refused to speak first and made Kim do all the talking. This incident has left Kim incredibly upset and she feels disappointed with what happened."
A spokesperson for Loose Women said: "Kim agreed to come onto the panel today at the invitation of the producers on the understanding it was for a reconciliation with Coleen.
"Kim becoming upset was never the intention and the panel did endeavour to comfort her. She was offered counselling after the show, which she declined."
In the aftermath, viewers called for Coleen to be sacked from the show.
Appearing on This Morning shortly after the incident, Coleen said: "I honestly don’t know what to say. If I could go back in time, I would change the whole thing. It was never meant to be like that, I thought Kim was coming on to make amends.
"It didn’t go that way obviously from the moment she came out. It was genuinely shocking for the both of us. I didn't want anyone to be distressed. It’s been the worst week of my life."
Loose Women airs weekdays at 12:30PM on ITV.
