Some of I'm A Celebrity line-up has been leaked a week ahead of the first show being aired on ITV later this month.
Keeping Up With The Kardashians star Caitlyn Jenner will lead the celebrities after she was paid £500,000 to persuade her to venture into the Australian jungle, the Mirror reports.
Among the celebrities taking part are Radio 1 DJ Adele Roberts - who found fame after she starred in Big Brother - and Myles Stephenson from Rak-Su, whose band won the X Factor in 2017.
Good Morning Britain presenter Kate Garraway and former footballer - turned pundit- Ian Wright are also tipped to be heading for the jungle, in the show presented by Ant and Dec.
American reality star Caitlyn, aged 70, will fly to Australia later this month from the US, it is reported.
Caitlyn was once known as the world's greatest as she won gold in the decathlon at the 1976 Olympics, before gender reassignment, when she was known as Bruce.
Bruce had a total of six children with three wives and became a reality TV star during the marriage to Kris Jenner, as a member of the Kardashian clan.
Caitlyn has appeared on Keeping Up With The Kardashians since 2017, alongside her now ex-wife Kris, daughters Kim, Kourtney and Khloe and their two daughters Kris and Kylie Jenner.
She came out as a transgender woman four years ago and announced her name change to Caitlyn in a cover of the glossy magazine Vanity Fair.
Good Morning Britain presenter Kate Garraway, 52, was tipped to enter the jungle last year but was said to have pulled out of the series just weeks before filming was due to start.
She was teased about kangaroo testicles by her GMB co-host Ben Shephard, which gave a massive hint that she was probably heading into the jungle this year.
Former footballer turned pundit Ian Wright, 55, could be one of the sports stars in the camp, and is said to be in 'advanced talks' with the producers, which he is attempting to fit in around his busy schedule as the football season continues.
Girls Aloud singer Nadine Coyle, DJ Roman Kemp and rugby player James Haskell also join the line-up, according to the Sun.
Previously, Coronation Street star Andrew Whyment, who plays Kirk Sutherland, and Love Island's Olivia Attwood were rumoured to be heading for the jungle.
A spokesperson for ITV told the Mirror: "We'll officially announce our I'm A Celebrity line up for 2019 in due course."
Host Declan Donnelly has already arrived in Australia with his wife Ali and their baby daughter.
He will be joined for the first time since 2017 by Ant McPartlin, who was replaced last year by Holly Willoughby, after he took time out after he was caught drink-driving.
Last year, former England football manager Harry Redknapp was crowned King of the Jungle after beating off competition from actor John Barrowman and Emily Atack.
Spin-off show Extra Camp sees Emily Atack and Adam Thomas to join Joel Dommett as new hosts.
