A British morning host has slammed a bridesmaid for “deliberately sabotaging” her sister’s wedding.

When a bride called into the This Morning program to complain about her sister’s poor bridesmaid effort, host Vanessa Feltz was quick to weigh in on the debacle.

The woman by the name of Gabby told Feltz that she had got married in November last year and (her sister) was maid-of-honour.

“She was invited to the rehearsal and I only had her and my cousin as bridesmaids. She didn’t come to the rehearsal but my cousin did,” the newlywed said on the program.

“So the vicar showed my cousin how to take my flowers and sign the register and because my sister didn’t get that part, we no longer speak.”

The bride’s sister felt that she was being “pushed out” in favour of the cousin.

“She felt like it was all about my cousin and didn’t see the point that it wasn’t about my cousin, it was about me and my husband — it was our day.”

On the day of the wedding her sister turned up late to her house for the morning preparation.

“She hadn’t even showered or anything. There was literally no effort made, she just arrived.”

When she asked Feltz if she was being “unreasonable” for refusing to speak to her, the straightforward host responded: “What exactly are you worried about?”

“Because we’re not speaking and we’ve never really had a fall out before and I don’t know whether to offer an olive branch or whether just let her come to me this time,” the bride answered.

Feltz said the woman wasn’t being unreasonable for not speaking to her sister after she failed to turn up to rehearsal and was late to the wedding.

Feltz sympathised with the anonymous woman, and seemed outraged at how her sister handled the situation, saying it sounded like she was “deliberately sabotaging” the wedding “in every way possible”.

“Who turns up late, unwashed, unshowered to their own sister’s wedding making the bride late for her own wedding?” Feltz asked the woman.

“Who doesn’t go to the hassle if she’s one of the only two bridesmaids at the wedding … everyone watching would agree it’s downright nasty.”

She told the woman that her sister’s actions were “callous, disrespectful, really rude and hurtful”.

It doesn’t look like the sisters’ feud will be mended any time soon.
