TLC Series 'Extreme Sisters' Follows the Most Obsessive and Inseparable Sibling Relationships

The new TLC series will follow five sets of sisters, taking a look at just how extremely close sisters can be.

TLC's new seriesExtreme Sisters, takes sibling bonding to a whole new level. On the network's latest reality showExtreme Sisters will follow five of the "most obsessive and inseparable sibling relationships" between sisters, Anna and Lucy, Brooke and Baylee, Brittany and Briana, Christina and Jessica, and Patrix and Patricia.

"Some sister bonds are closer than others, but these siblings take their obsession to the extreme. From eating the same foods, to sleeping in the same bed and even sharing a boyfriend, some of these sister fascinations are sure to make you think twice about how close sisters can really be," the press release states.

In the exclusive trailer for the series, we see these sisters do exactly that, with sisters Anna and Lucy seeing themselves as one in the same. 

"We just see ourselves as one person," the sisters share.


And while some of the sisterly activities seem extreme -- Brooke and Baylee reveal that they share underwear! -- Howard Lee, President of TLC Streaming and Network Originals, calls the relationships between these siblings "raw" and "honest."

“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," Lee said of the series.

While these sisters are confident in their closer-than-ever bonds, the show will take a look at what happens when the opinions of society, their family, friends and partners come into play and if their sisterly connection is strong enough to withstand the pressure.

Extreme Sisters premieres Sunday, April 25 at 10 p.m. ET/PT on TLC.
