Caitlyn Jenner will be taking part in the 2019 series after being offered the highest fee in the competition’s history.
Reports suggest that she will be paid a record £500,000 to enter the Australian jungle, with the series set to get underway on Sunday evening.
Express Sport have now taken at look at the 70-year-old’s journey from Olympic athlete to I’m a Celebrity contestant.
Caitlyn Marie Jenner was born William Bruce Jenner in October 1949, and began to take part in decathlons after a knee injury put an end to their American football scholarship at Graceland College.
Jenner qualified for the 1972 Summer Olympics in Munich and went on to finish in tenth place, before being inspired to step up their training routine.
Jenner said: “I literally started training that night at midnight, running through the streets of Munich, Germany, training for the Games.
“I trained that day on through to the 1976 Games, 6–8 hours a day, every day, 365 days a year.”
That intense training schedule paid off as Jenner went on to follow up gold at the 1975 Mexico City Pan American Games with the same medal at the 1976 Summer Olympics in Montreal.
Jenner achieved five personal bests on the opening day of the men’s decathlon in that tournament, and went on to set a world-record score of 8,618 after the second and final day.
Following their athletics career, Jenner has appeared in films and on television was reportedly considered for the role of Superman, which went to Christopher Reeve.
In what would turn out to forge a career in reality television, Jenner married for the third time in 1991, this time to Kris Kardashian.
Jenner went on to have two more children, after having Burton “Burt” Jenner and daughter Cassandra “Casey” Marino with Chrystie Scott and Brody Jenner and Brandon Jenner with Linda Thompson.
Jenner’s youngest daughters, Kendall and Kylie Jenner, have gone on to create multi-million dollar reality empires, with the latter becoming, in her own words, the world’s youngest billionaire.
Jenner was also the step-parent to Kourtney Kardashian, Kim Kardashian, Khloe Kardashian and Rob Kardashian and has regularly appeared on the television show Keeping Up with the Kardashians.
In January 2017, Jenner underwent sex reassignment surgery after coming out as a trans-woman in 2015, and starred in her own reality show I Am Cait.
Jenner was part of the cast of the American version of I’m a Celebrity…Get Me Out of Here! back in 2003, as actor Cris Judd went on to be crowned the victor.
