The producers of British reality series I’m a Celebrity … Get Me Out of Here! are seeking alternative ways to accommodate three vegan celebrities who have signed up for the new season, which airs this weekend, according to media outlet The Daily Star. The show is known for forcing contestants to undergo gruesome food challenges (known as “Bushtucker Trials”) that include eating animal parts such as kangaroo and bull testicles while fending for themselves in an Australian jungle. The three vegan celebrities to appear on the show are musicians Fleur East and James McVey, and actor Sair Khan, all of whom are unlikely to take part in the challenges. “It could prove a bit tricky for bosses if they refuse to do the eating Bushtucker Trials,” a source told The Daily Star. “Fleur has already told bosses that she is strictly vegan and does not go near any animal products. It’s certainly not ideal.” I’m a Celebrity has faced criticism over its use of animals in the past. In 2014, wildlife expert Chris Packham wrote an open letter to the show’s producers, asking them to “put an end to this inhumane, embarrassing and destructive aspect of an otherwise great show.”
