If you’ve ever been a bridesmaid or just gone to a wedding as a guest, you know it can be uber stressful. What gift should you get the happy couple? Will you be able to book off that long weekend for the bachelorette party? That’s why it doesn’t make things any easier when the bride makes wacky wedding demands of her bridesmaids or guests.

Celebrity health guru Rainbeau Mars will be getting married soon, and she’s asking her guests for one teensy favor: she wants everyone to go on a three-week cleanse before the nuptials.

“Rainbeau hopes that by requesting her guests try out a vegan, and subsequently live food diet for 21 days, everyone will look and feel their best for HER big day,” writes her publicist.

Cleansing involves ridding your body of so-called toxins by avoiding certain foods, fasting, dieting or consuming specific foods. If it’s done properly, cleansing is harmless, but if done improperly, it can lead to fatigue, dizziness, dehydration, and colon damage.

Is this wedding demand a severe case of Bridezilla or is it not really that bizarre? We’ve come across a few outlandish requests and behaviors from brides in the past, like demanding botox injections for the father of the bride or sending out crazy emails to bridesmaids-to-be and demanding all their waking moments be occupied by visions of that super duper special day.

“I’m not going to harass you with wedding stuff every hour of everyday but if its something important and it takes you a week even 2-3 days to get back to me seeeee ya!” wrote one anonymous Bridezilla.

Ugh, I thought weddings were supposed to be a celebration of a couple’s love. Why make your “special day” something people will dread?
