There's little that challenges a person's sanity quite like planning a wedding. That's clearly been the case of a recently famed bride-to-be who has been labelled a "bridezilla" after taking to the internet to vent at the news that one of her bridesmaid's was pregnant.

Hitting up online forum page, Reddit, the unidentified woman posed the question; "Am I allowed to be pi**ed or am I just selfish?" when it came to her reaction at the baby news, citing her concerns bout how it would impact the upcoming hens night.

"Long story short, I just found out that one of my bridesmaids will be 5-6 months pregnant on my wedding day," pens the bride-to be.

"This bridesmaid was also planning my super secret bachelorette party that I know no details of, but I'm assuming involved drinking that will probably either be changed or cancelled."

Ah, the narcissistic blinkers of a bridezilla are narrow, indeed.

Clearly in a battle with her pre-bride common sense, the woman went on to write; "Maybe I'm just thinking the worst here, but personally I think it's wrong to get pregnant when you're part of the bridal party and not tell the bride…"

And, boy, did the people of the internets let her know exactly what they thought of her reaction … and let's just say they weren't on the same page as her.

"It's not wrong to get pregnant if you're going to be in a bridal party," announced one commenter. "You can't ask someone to put their life on hold for your wedding. You are being selfish."

Another was quick to jump in with a suggestion for a more appropriate response to her pregnant friend. "Is it possible that she didn't tell you because she knew your reflex reaction would NOT be "Congratulations! Let's get you a bridesmaid's dress that is comfortable!" but instead, "This is going to f**k up my bachelorette party"?" they asked.

"It's good that you are entertaining the idea that this reaction is selfish. It means that there's hope you won't bridezilla all over the place," the commenter continued. "I think you should send her some congratulation flowers with a note about how excited you are for her."

More wisdom came from another commenter keen to point out why the pregnancy had bee kept a secret.

"Many people wait until the first trimester is over to tell people, because if they lose the baby, it's devastating to have to tell excited people over and over again that your baby died. When my spouse and I were expecting, we didn't even tell our parents until the first trimester had passed. So no, your bridesmaid was not obligated to tell you anything."

"Your bachelorette party is just one night. Your friend's pregnancy is the creation of another human that will last a lifetime," said another.

Many commenters suggested she simply speak to the bridesmaid in question, rather than dwell on the details that she's simply assuming will happen.

"You don't know the details of the party; you're just making assumptions. If you're concerned or have specific desires for the event, talk to your friend and make them known," suggests one commenter. "The event may still involve drinking, but she'd likely just abstain."

Once again, the good folks of the internet, with their infinite wisdom and brutal harsh truths prove to be the perfect antidote to 'bridezilla-itis'.

What do you think, are bridesmaids obligated to tell brides if they are expecting more than bad speeches on the day of the wedding?
