Hey, soon-to-be-married people: Before you start drafting out your guest list, you might want to leave a couple extra spots for two very unexpected guests.

As multiple sources report, it is now possible for spouses-to-be to rent out therapy llamas for their big day thanks to the Instagram sensation the "Wedding Llamas," and the second you see them, you'll want to invite them to your wedding, too.

For those in the Portland, Oregon and Vancouver, Washington areas, Mountain Green Therapy Llamas and Alpacas has begun offering up seven of their service animals for weddings, both to help calm nerves, and to help couples celebrate in style. Even better, the animals love getting to attend these weddings, and dress to the nines for every event — thus somehow managing to bring even more joy and love and excitement to a day already filled with all three.

As HelloGiggles reports, the "Wedding Llamas" spend most of their days doing service work with children and older people. But they're also very sociable creatures outside of their work, and keep a busy calendar with other events, too.

If you're somehow still not sold on having llamas at your wedding yet, you should probably know that all the proceeds that come from renting them will go directly back to the charity and its mission to spread the llama love. And isn't love what weddings are all about?!
