The model will be one of seven celebrities taking part in I'm A Celebrity, Get Me Out Of Here, which will begin on August 24 and run for two weeks in the setting of the Australian Outback.
"Paul had too many other commitments so we brought in Nell to add glamour," an insider told the News Of The World today.
Melinda Messenger has also been dropped from the lineup in favour of Darren Day. Other celebrities taking part include Christine Hamilton and comedian Ed Byrne.
