BIG Brother fans will be used to it by now - first comes the eviction, then the tell all story and photo shoot followed by the autobiography.

But ex-Big Brother seven housemate Lea Walker has been putting her 15 minutes of fame to good use promoting awareness of body dysmorphia.

The 38-year-old, who suffers from the mental illness and subsequent surgery addiction, was in Swindon’s Borders store in the Orbital Retail Park, on Saturday signing copies of her book Living With BDD.

“When I was on Big Brother I was just a freakshow,” said the mum-of-one from Manchester.

“I had the bleach blonde hair and the big boobs and wasn’t taken seriously. BDD isn’t like other body dysmorphic disorders like anorexia and bulimia, it’s not seen as a real problem.”

Body dysmorphia is an umbrella term for mental illnesses which create a distorted perception about the sufferers body.

“Some people have eating disorders, others have skin dysmorphia and will cover themselves in tattoos and some, like me, feel the need to have surgery to continually ‘improve’ themselves,” said Lea, who was diagnosed in 1995.

In the last 12 years she has had three nose jobs, teeth veneers, cheek implants, lip implants, five breast enlargements, lipo suction, lipo sculpture three times and a tummy tuck but her surgery hasn’t stopped yet as she still plans to have a facelift, thigh lift and buttock implants.

Lea’s book Living With BDD: Body Dysmorphic Disorder is out now priced at £16.99.
