I'm A Celebrity 2021 stars will do two week quarantine before entering Gwrych castle
ITV bosses have confirmed the line-up will follow the same procedures as last year with regular Covid-19 testing taking place too.
It's not known who has been cast for this year's series, but rumours include Good Morning Britain's Richard Madeley and former Strictly Come Dancing judge Arlene Phillips, 78. You can see the rumoured line-up in full here.
You can also see a full list of those who have ruled themselves firmly out of the running, including Katherine Jenkins and Denise van Outen, here.
A source told The Sun: "All of the celebrities will have to quarantine alone for a fortnight.
"Once this ends they will enter the camp, which is basically then their bubble for the whole series. Testing will be done regularly in camp and on the set to ensure all the cast and crew are safe.
"ITV thinks this is the best case scenario and will stop any headaches surrounding Covid, which has been a nightmare for the BBC with Strictly."
It comes after Strictly Come Dancing's Tom Fletcher and Amy Dowden tested positive for Covid-19, with the pair forced to miss the second week of live shows due to isolation.
Speaking to WalesOnline an ITV spokesperson said: "Like last year, our celebrities will do a two week quarantine with regular testing prior to entering the castle, and will then form a bubble for the duration of their time on the show."
I'm A Celebrity is set to return to Gwrych Castle in Abergele and not the Australian jungle for the second time in November. You can read more about the rumoured 2021 start date here.
ITV bosses said the decision to host I'm A Celebrity in Wales again was due to the "continued uncertainty" around Covid-19 and international travel, and a "highly successful run" last year which saw Giovanna Fletcher win.
