LANDLORD Rod Yeandle told jurors of his shock after one of his customers was hit in the face with a glass at an engagement party.
Mr Yeandle took the stand at Gloucester Crown Court, where Jennifer Eckley is on trial for attacking bride-to-be Lucy Steers, 28.
The George Hotel, Newent, landlord told the court he was trying to calm down 27-year-old Eckley, of Foley Road, Newent, moments before she hit Miss Steers.
He said he had taken Eckley, whom he has known since she was 12, outside to try to calm her down after the women had an altercation at the bar.
Mr Yeandle said in his statement there was a glass in her hand while the pair were talking just moments before the attack on December 1, last year.
He said: "I just didn't expect what occurred to happen. I just could not believe what was happening."
Eckley denies wounding Miss Steers with intent to cause grievous bodily harm and took to the stand herself yesterday.
She told the jury she had been out on a hen party that evening. She said she had been on anti-depressants since she appeared on the ITV show Jeremy Kyle two years ago with her former boyfriend.
She told the court when she spoke to Lucy at the bar she mentioned the television appearance. She said: "I said 'I'm glad you find my pain funny'. I said 'you don't know what I have been through' and I started to get cross."
She said the pair exchanged expletives before Lucy's father, Geoffrey stepped in, who was also swearing at her.
She told the jury: "Then I heard her shouting about the Jeremy Kyle show again and I could not see her, but I could hear. I stormed around the corner and she was laughing at me – grinning and laughing in my face.
"Her friends were there and they were surrounding me, calling me names, they were cackling.
"We both stepped forward and both flew our arms in the air and the next thing I knew Rod was dragging me off around the corner. I promise on my life that I never ever meant for that to happen. I would never do that. Glassing someone for just shouting Jeremy Kyle show is just stupid."
The court previously heard that before the alleged glassing, Eckley grabbed party guest Nicola Taylor's hair, and banged her head against the wall after realising she was the former partner of her then boyfriend.
Eckley admitted assaulting her, but denied punching Nicola's sister, Kate, when she tried to intervene.
The trial continues.
