The former X Factor star became the 'Queen Bee' after answering Big Brother's call and was given 15 words related to the insects that he would have to correctly repeat back.
If he succeeded in spelling ten, Cocozza would win a luxury party for the house, while five correct answers would see Big Brother supply them with alcohol.
However, for every word spelt incorrectly, the housemates would be punished with a 'celebrity sting'.
Cocozza successfully managed to spell seven of the given words, but stumbled over terms such as chrysanthemum, chlorophyll and dandelion.
Housemates also passed their 'Big In Japan' task this weekend and were rewarded with a sushi party.
Gareth Thomas previously won back his letter from home after passing a pep talk challenge before Friday's double eviction.
