A British bride who had black paint thrown over her just before she walked down the aisle broke down in tears Tuesday as she ripped her sister-in-law’s attempts to justify the spiteful attack.

Gemma Monk, 35, sobbed on “Good Morning Britain” as she revealed the heartbreak of the wedding-day attack that ruined her $2,400 dress — and the ongoing pain of her brother’s wife, Antonia Eastwood, trying to blame her for a simmering feud even after she was convicted for the cruel attack.

“Things have been taken out of proportion in the reason why she did this,” Monk said after Eastwood accused her of starting it by jealously trying to trip her at her own wedding years earlier.

“All the allegations she has put forward are all false,” Monk insisted in her tearful TV interview Tuesday, according to the Mirror.

Sitting beside her husband, Ken, Monk cried as she recalled how what was supposed to be the best day of her life turned into a nightmare.

“I was getting ready, my dad came to collect me, and I arrived down the road from the venue because the guests were still outside,” she said.

“We waited down there before we went in, and when we got the ok, my dad drove me and my bridesmaids to the venue. We got out and had a photo with the photographer, and I was then told not to get out here, and we were going to the bridal tour,” Monk continued.

As Monk went to enter the venue, she heard her name being called — before realizing black paint had been thrown over her.

Shocking photos showed the devastated bride-to-be with dark, mud-like paint covering the left side of her face and chest and spattered across her $2,400 white dress.

“I knew instantly who it was. There’s not many people I don’t get on with. I’m not a hated person; I’ve got a kind heart. I only want what’s best for my brother,” she said.

Ken, who was standing at the altar oblivious to the commotion outside until he was told by the registrar, said he also instantly knew who was behind it.

Hairdresser Eastwood claimed in an interview following her sentencing that her bizarre stunt was the result of years of simmering tensions and jealousy between the pair, which she said had begun when she started dating Monk’s brother in April 2023.

She accused Monk of being jealous when her brother, Ash, proposed to Eastwood after just five months of dating, as her own partner of more than 20 years still hadn’t asked her to tie the knot.

Monk then set about trying to sabotage her sister-in-law’s wedding, Eastwood claimed, accusing her of ousting her best man and trying to trip her as she walked down the aisle.

Despite both being banned from Monk’s wedding, Eastwood and her husband still showed up, where she admitted in court to throwing the child-safe black paint at the bride outside the venue in a “spur of the moment” attack.

Eastwood was handed a 10-month prison sentence, suspended for 12 months, the UK equivalent of parole. She was also ordered to do 160 hours of community service.

Monk and her husband went through with their wedding after an emergency clean dress was found.

The couple plans to renew their vows next year — with tighter security in place this time around.
