We've heard many tales over the years of demanding brides' unreasonable expectations for family members, friends, bridesmaids… the list goes on.
But one US bride might just take the cake, firing her own four-year-old niece from her wedding, due to "poor performance".
The bride's sister took to Reddit to explain she was initially nervous when her younger sister asked her and her four-year-old daughter to be bridesmaids at her wedding in February "because I knew she was gonna be a massive bridezilla".
"I'm gonna be blunt, my sister has always been one of those people that has to have everything perfect to the point sometimes it was hard to be around her - but she was my little sister and I've no other siblings," the woman wrote.
The sister wrote that the last few months had seen the wedding party "practice multiple dances, pay for very expensive dresses and put up with her tantrums".
"I told her from the start if she was any way nasty to my child I wouldn't stand for it," she wrote. "She assured me she'd never be nasty towards her 'favourite person in the whole world'."
But the sister's concerns grew when the groom's little cousin started coming to dance practice.
"My sister started to ask her to do little things like show my daughter how to throw the petals," she recounted.
"I honestly thought she'd make them both flower girls for a while but when she started to make my daughter sit out and have the little girl do her poem, I knew what was gonna happen.
"I prayed I was wrong."
In the end, the sister took the bride out to coffee and asked her what was going on.
"She told me she was glad I brought it up because she was looking for the right time," she wrote.
"Apparently my four-year-old wasn't doing everything right and she was afraid she was gonna 'mess up her vision' by saying the wrong thing or not doing the dance right on the day."
The concerned sister ended up asking the bride outright if she thought her niece wasn't "good enough" to be in the wedding.
"She replied with 'not as something big as a flower girl but [she can] attend'.
"I asked her how I was going to break it to my daughter who's excited about being in the wedding. She just told me 'figure it out'.
"I told her I'd give her a day to rethink her decision [and] if not we wouldn't [be] attending or speaking to her ever again, then left."
The Reddit user was forced to break the heartbreaking news to her daughter, who "cried herself to sleep".
"So did me and my husband," she added.
The Reddit user said she'd told several people what had happened, which led family members - including bridesmaids - to drop out of the wedding.
"We ended up going for a few weeks away with no phones. When we came back my sister had sent me multiple letters and emails apologising. Her in-laws and husband have called me an asshole for doing what I did."
The post racked up over 2000 likes from shocked Reddit users, firmly reassuring the sister she wasn't in the wrong.
"This child is FOUR. Four years old. Her aunt kicked her out of the celebration because she might not be perfect. She's four," one person pointed out.
"Want to be such a raging narcissist that you don't care about emotionally scarring your little four-year-old niece and risking her never trusting you, oh and risking your relationship with your sister - over a flower girl role at your wedding? Well your wish has been granted," another wrote
"I wouldn't ever speak to her again either. Your bridezilla sister said 'figure it out' and you figured it out!" another pointed out.
In a later update, the sister revealed neither she nor her husband attended the wedding, and they still haven't spoken to the bride or groom.
