First up, Giovanna was given a fermented egg which she appeared to chow down on with not much difficulty at all.
Next up was a piece of a cow's nose and a fish eye - once again, Gi swallowed them down without gagging too much.
However, the next delicacy was a rather large sheep's testicle - and the 35-year-old appeared to take her time nibbling on it.
As hosts Ant McPartlin and Declan Donnelly asked Gi if the testicle "tastes lamby", she laughed and said not really.
Dec then asked if it "tastes testicly" to which Giovanna made a cheeky comment about other testicles she's tasted.
"Right, time for kids to switch off now. It's time for bed," Dec quickly said as Gi continued to eat her snack.
Viewers at home found the entire thing hilarious and took to Twitter to comment.
"Giovanna casually snacking on lamb testicle like it’s a scotch egg with a drink at a Wetherspoons #imaceleb," one person wrote.
A second person referenced Gi's husband Tom watching at home: "tom when giovanna said the lamb’s testicle didn’t taste like the testicles she’d had in her mouth before #ImACelebrity #ImaCeleb."
A third viewer wrote: "Giovanna basically admitted she’s had Tom Fletchers balls in her mouth while eating a lambs testicle #ImACelebrity #ImACeleb."
The moment could have made for some rather awkward viewing for McFly star Tom, who was watching the final at home with their young children.
As Giovanna took her time chewing the testicle, Ant and Dec began singing a rendition of the McFly hit 'All About You' which was written by Tom about Giovanna.
However, the hosting duo changed the lyrics to: "It's all about chew..."
