Two women are about to catch their cheating husbands. But there's a twist.

You may or may not have heard of a little Netflix show called Grace and Frankie.

It stars Jane Fonda and Lily Tomlin, and centres on the friendship between two women who are forced to unite when their husbands – who are also business partners – announce they are in love and plan to marry.

While not an entirely ridiculous notion, the tale of two wives whose husbands leave them for each other is one we regularly file under ‘fiction’. Until now.

You see, while waiting to board a flight, filmmaker and writer BJ Colangelo overheard two women who were on their way to bust their husbands cheating... together.

There are two women next to me at the airport bar who are flying cross-country to ambush their husbands they think are sleeping together.

Naturally, because it's 2017 and nothing is sacred, she decided to live-tweet the entire interaction.

The women have never met until this moment. "Hopefully I'll gain a sister in you if I lose my husband."

I am going to live-tweet the fuck out of my eavesdropping.

The women begin by discussing their dismay that their husbands can't live honestly - "I don't care if they're gay...I care they lie" - before they order a round of shots.

This is where the fun begins.

LISTEN: This woman's ex husband is now cheating on his mistress with another girlfriend. Should she whistleblow or walk away?

One woman - who earns herself the nickname 'shot lady' from BJ - reveals her daughter's boyfriend once held suspicions her husband might be gay.

"I thought he was an asshole. I guess he's just clairvoyant."

She ordered another round.

The pair then discuss Halloween, and show off pictures of their grandchildren all dressed up. One woman remarks their husbands "should have dressed as Bert and Ernie".

Then, they look at pictures of baby hippos. Because, when you're faced with infidelity, sometimes a chubby, infant animal is the only thing that can cheer you up.

One of the ladies is fighting back tears, telling her new best friend the other, "I'm so glad you still have a sense of humour".

Shot Lady: "Our husbands are fucking, or we're both insane. Either way, were going to be okay. I promise." ADOPT ME SHOT LADY.

They're cashing out. Gum lady is laughing. Shot lady is holding her hand. I'M GOING TO CRY.

As the women prepare for their flight, their friendship is cemented.

Gum Lady: "At least my husband's boyfriend has good taste in women." Shot Lady: "Yea. You're pretty okay too." THIS IS 100% GRACE & FRANKIE.

Shot Lady: "We can do this." Gum Lady: "You're right. We can." Shot lady pounded something dark. They have left me.

The story ended with a dire warning for the men at the centre of the sordid tale:

If your names are Jeffrey and and Richard and you're on a "business trip" in Chicago...your wives are coming for you. And they've bonded.

The tweets, which have been re-tweeted and liked thousands of time, have sparked the curiosity of the Internet, with many readers now desperate to know the outcome of the trip.

PLEASE FOLLOW THEM TO CHICAGO!! I NEED TO KNOW HOW THIS ENDS!!

Here's hoping we get a sequel resolution sometime soon... Until then, we're glad to see the sisterhood is still alive and well.
