Katie Price's son Harvey Price attempts Guinness World Record

The 21-year-old has Prader-Willi Syndrome, autism and is partially blind. He was also born with Septo-optic Dysplasia, which affects around one in every 10,000 births.

Harvey, along with ten of his friends who also have learning disabilities, is aiming to draw a 20m long and 1m high train over the course of one month, making it the world's longest train drawing.

Mencap, a UK charity for those with a learning disability, showed their support and wished Harvey luck.

They said: “Harvey, alongside ten friends from his residential college who also have learning disabilities, have begun their attempt to draw a 20m long and 1m high train and aim to complete it in over one month.

“Good luck to Harvey and everyone involved!”

Brighton's Katie Price expressed her pride on her Instagram page.

She said: "So proud of@officialmrharveypricewho will begin his own @guinnessworldrecordsattempt for @mencapLearning Disability Week."

Harvey, who was born with Septo-optic Dysplasia, recently celebrated his 21st birthday.

His sister, Princess, is set to turn 16 at the end of this month.

Peter Andre and Katie Price are reportedly in 'competition' as they try to organize the most extravagant birthday party for their daughter.

The two parents are allegedly locked in a battle, each trying to give Princess the most memorable bash for her 16th birthday at the end of this month.

Glamour model Katie Price has allegedly planned a Grease-inspired funfair celebration at her Mucky Mansion, while Peter is organizing a prom-inspired party at his huge Surrey mansion, a source told The Sun.

Peter is said to be sparing no expense as he employs caterers, DJs, and a huge marquee to host Princess and her friends.

A crystal embellished cake is set to be the centrepiece at Katie's party, with guests wearing tiaras for the occasion.
