A beauty pageant where the only contestants are women with breast implants and facelifts suffered an unexpected setback when the favourite collapsed under the weight of her silicone chest.

Beautiful blonde Alexandra Horvath, 23, stumbled and fell off her stiletto heels under the weight of her silicone implants.

The implants caused Alexandra to lose her balance as she strutted her stuff in six-inch high heels.

She toppled off the catwalk shortly after parading in front of judges — tearing a ligament and ending up in hospital.

A friend said: 'She had not got used to the extra weight on top and her new hair extensions got in her eyes - she just lost her balance and tore a ligament in her foot badly.'

Miss Plastic features ‘Man Made’ patients of the country’s leading surgeons showing off everything from boob jobs and liposuction to hair transplants.

Reka Urban, a 22-year-old hostess from Hungary, won the contest in her home country last weekend.

The contest was organised by doctors and women who had cosmetic surgery but were angry about being banned from conventional beauty contests.

Two of the 20 finalists had previously been thrown out of pageants after judges found they had false boobs.

The pageant’s organiser Miss Reka Bodis said: “The entry requirement is a surgical procedure done under general or local anaesthesia.

“Unfortunately, Hungarians are still negative about cosmetic surgery and a lot of stereotypes are going about.

“We are not seeking to promote extremely large breasts and the like.”
