It’s usually the celebs that end up vomiting on I’m A Celebrity … Get Me Out Of Here!

But this time, it was Dr Chris Brown that couldn’t keep his food down.

Freddie Flintoff had the task of chowing down on critters during Tuesday night’s tucker trial.

He managed to down a giant snail, a cockroach and a rats tail but had to bow out when served a “critters jungle juice” — a smoothie of cockroaches, worms, fly pupae and crickets.

That’s when Dr Chris Brown decided to step in and see for himself how bad it was.

And it wasn’t good.

Dr Chris had to walk away to vomit into the bushes — leaving his co-host, Julia Morris, to manage the rest of the challenge.

That’s when Freddie stepped in to offer a rather robotic impression of the Bondi Vet.
