But before he watches his elder brother James, 41, walk down the aisle of St. Marks’s church in Englefield to tie the knot with Princess Kate‘s 33-year-old sister, the ex-Made In Chelsea star first has to survive the riskiest reality show on British TV.
Matthews is currently training for the bone-breaking winter sports show The Jump in Innsbruck, Austria. The show — which runs for six weeks, starting February 5 — pits celebrity contestants against each other in a series of high-risk sports such as the skeleton, ski cross, bobsleigh, downhill slalom and snowskates.
Those who haven’t sufficiently mastered the sports and finish bottom of the weekly leader board then have to fight for survival by performing a terrifying ski-jump on live TV. The celebrity that jumps the shortest distance — or lands in the biggest crumpled heap — is then eliminated from the show.
The list of injuries from the previous three series has been horrendous: The Jump has only been allowed back on Channel 4 following a “thorough review of safety standards,” according to a statement.
Last year’s competition alone saw seven celebrities receive hospital treatment after nasty accidents. They included Olympic bronze medal-winning gymnast Beth Tweddle, who fractured two vertebrae in her back after crashing into a safety barrier.
Fellow British Olympian and double gold-medal swimmer Rebecca Adlington also dislocated her shoulder, while former Dancing with the Stars contestant (and Paul McCartney’s ex wife) Heather Mills suffered severe knee ligament damage.
Matthews’ Made in Chelsea costar Mark Francis Vandelli also broke an ankle after tumbling midway through the “snow cross” challenge, requiring 16 stitches and two operations in the process.
The future royal brother-in-law is no stranger to attention-grabbing stunts: In September, he posed nearly nude in a London shop window to promote an online fashion retailer.
