Adult sisters slept in the same bed at home even after one of them got married

Adult sisters Brooke and Baylee are so close that they share the same bed - even though Brooke is married.

It must have been tough for the inseparable sisters when Brooke, 24, moved in with her husband Denver, 27. But when Baylee, 22, decided to move in with them, things got a little too close for comfort.

Baylee and Brooke, who appear on TLC's Extreme Sisters, have four other siblings, but have a particularly special bond with each other.

Because they had a blended family they explained, they've been 'by each other's sides' for most of their childhoods.

And, as they got older, that never really stopped.

"When we were kids no matter where we stayed Baylee and I always shared a bed. It was just kind of our safe space with each other," says Brooke.

Things get particularly awkward when Baylee moves in with Brooke and her husband Denver, and the sisters decide they still need to share the same bed - with Denver inside too.

"You knew what we were getting into when we were getting married," Brooke tells her husband casually.

Denver, who looks like a deer in headlights, replies: "I don't agree... I didn't know that she was going to be living at our house."

Confronting the sisters during their first appearance on Extreme Sisters, Denver tells them: "Three out of the last four nights, I'm pretty sure your sister has been in our bed... that's ridiculous."

While the sisters argue that there should be no problem since Baylee isn't cuddling or touching her brother-in-law in bed, they agree to try and make a compromise.

But instead, they try to sneak Baylee into the bed when they think Denver is asleep.

It's during this scene in the show when viewers realise that, not only does Baylee sleep in a bed with her sister and sister's husband, but she sleeps in the middle.

And a bed isn't all these two sisters share, either.

You'll be absolutely shocked to learn that Brooke and Baylee have also shared underwear, razors and toothbrushes.

"A lot of people are shocked that we have shared underwear. It's not that crazy at all. Sometimes you just have to grab and go!" Baylee told Fox News in an interview.

And Brooke agreed: "Oh my god, the thing I love about the show is it shows the realness. So whether people want to admit it or not, they're sharing underwear. If they're saying they're not, they're liars."

On toothbrushes, she added: "I mean, if you have to get out of the house and you only see one toothbrush because yours is missing, you just are going to grab whatever you see!"

Baylee agreed: "It's better than having bad breath!"

Is it, though? Is it really?
