**CONDITION OF USAGE - Body Bizarre is on Saturdays at 10pm on TLC UK.** *** EXCLUSIVE - VIDEO AVAILABLE *** COVENTRY - UNDATED: Head shot of Alex Barker and Erin Smith who both have Moebius syndrome, sitting in a park. A MAN and woman who have bonded over both having the same condition which means they can?t smile have become a COUPLE. Alex Barker, 45, from Coventry and Erin Smith, 38, from North Carolina, were both born with Moebius syndrome, a rare condition which causes paralysis of the cranial nerves, meaning sufferers can not make any facial expressions. It also affects their speech, as well as their ability to move their eyes or even blink. The condition is very rare, with only around 250 people with it in the UK and less than 1,000 worldwide, but Alex and Erin found love after meeting on a social media site for people with Moebius syndrome. And despite only meeting four times, they are already engaged. PHOTOGRAPH BY Discovery / Barcroft Productions
