Abby and Brittany Hensel
Conjoined twins Abby and Brittany Hensel to star in their own reality show TLC

Conjoined twins Abby and Brittany Hensel are to star in their own reality TV show.

The series will follow the 22-year-old sisters, who are dicephalic parapagus twins, ie joined at the neck, as they graduate from university, hunt for a job and travel through Europe with friends.

The Hensel sisters found fame at the age of six when they appeared on the Oprah Winfrey Show and graced the cover of Life magazine.

The reality show will be their third stint on TV. They have already starred in documentary Joined For Life and a follow-up programme, Abby and Brittany Turn 16.

The girls each have a separate heart, lungs, stomach and spinal cord but share most organs below the navel including intestine, bladder and reproductive organs.

While Brittany controls the right side of the body, Abby steers the left .

They made headlines in 2009 when an unsubstantiated rumour emerged that then Brittany was engaged, raising speculation about their bedroom arrangements.

In a subsequent interview Brittany said: "We're gonna be mums, we just haven't figured out how its going to work yet."

TLC's Abby and Brittany premieres on 28 August.
