A pair of sisters have revealed that they are so close that they share a bed with one of their husbands and even swap underwear.

Brooke and Baylee may not be twins, but they are as good as, spending almost every waking moment together.

The sisters even share the same first name, Candace, as they are actually called Candace-Brooke and Candace-Baylee, and Brooke's daughter is named Candace-Ace.

Aside from their names the duo, who star in the new TLC show Extreme Sisters, share everything, from clothes right down to their razors.

Speaking in the trailer, Brooke says: "We share razors, sometimes a toothbrush, underwear - but who doesn't? What sister doesn't share underwear?

"(Growing up) we shared the same room, we were always together and we always slept in the same bed."

"We're still doing that," Baylee adds.

In fact, Baylee will regularly crawl into bed with Brooke and her husband, much to his horror.

In the trailer Brooke's husband admits that Baylee's "welcome has been overstayed".

"I don't want to have to choose between my husband and my little sister," Brooke sobs.

Speaking ahead of the show's release Howard Lee, president of TLC, said: "Having a close knit family is something most people aspire to and at TLC, we love to explore relationships of all kinds.

"In Extreme Sisters, we will introduce sets of inseparable sisters whose bonds are raw, honest, and perhaps a little unconventional.

"Their sibling kinship brings the meaning of sisterhood to a whole other level."

Extreme Sisters premieres Sunday, April 25 on TLC, available via Foxtel.
