Blind dates arent just for romance anymore.

1 person for their entire lives was even trickier and more important than ever.

This story lives and dies on the chemistry between the two actresses playing the parts, Byrne tells EW.

I knew Tiffany from her work, and I was just such a fan.

We chatted on the phone and were like, Lets get a drink!

We had like a blind date and we really hit it off, the comedian says.

The idea of possibly working with Tiffany, I just thought it was thrilling.

I was so excited to meet her and be in a room with her, and hopefully hopefully!

I had no idea.

Like A Boss

It was literally a blind date.

Clearly it went well because here we are!

You could just have easily been talking to someone else if we hadnt hit it off.

Tiffs life is extraordinary she wrote her book about it,The Last Black Unicorn, she says.

She laughs, then adds, I immediately knew I wanted to do this [movie] after that.

I had never really read anything like it it wasnt about women talking about men, you know?

It was just about a friendship and business, and I hadnt seen that.

Haddish also laughs as she looks back on that super-cool date.

It was like a meet-and-greet, Haddish recalls.

We talked about ourselves, and we just got to know each other.

She was telling me about Australia, I was telling her about South Central L.A. We laughed a lot.

And as the drinks kept flowing, things… escalated.

She protected me, and thats when I knew she was a good friend.

She breaks off into laughter again and has to pause to catch her breath.

She made sure I got to my room!

Because I was pretty tipsy by that time.

Thats the story we made up in our heads of what would have happened.

Then I wouldnt have been able to make the movie because I would have been all pregnant.

Byrne saving her from pregnancy ultimately saved the movie, Haddish jokes.

I cook at my house and have a potluck Sunday, and she was there every Sunday.

I think its so important to really get to know someone, especially playing besties, Haddish says.

On and off camera.

And its like, God assigns you your mom and dad, your family, right?

But you could make your own family with your friends.

My friendships are forever.

And Byrne is happy to be a part of a movie that shes want to see in theaters.

And afterwards, call another friend and be inspired to reconnect with your girlfriends.

Like a Bossis in theaters now.
