With a banana, a belt and some oil to aid their performance, James and Austin gave Sherrie a very memorable 65th birthday surprise.
With Sherrie blindfolded on the chair, the housemates sat in a circle as James and Austin - who were introduced as Jaustin - came out from the store room to begin their strip tease.
Bobby Davro's facial expression was quite hilarious, and Natasha Hamilton and Stevi Ritchie appeared to be loving it as they clapped along.
Did the boys do the full monty? Yes, they certainly did.
With just hats protecting their manhood, Jaustin showed off their bottoms to their fellow housemates, and even slapped each other's as they finished off their show!
We reckon it'll be a night Sherrie will never forget! Watch the strip show in full here.
Tonight, all housemates face eviction, meaning Jenna Jameson, Farrah Abraham, James Hill, Sherrie Hewson, Austin Armacost, Chloe-Jasmine and Stevi Ritchie, Bobby Davro, Natasha Hamilton and Janice Dickinson are all at risk of leaving.
However, there will be a twist! The four housemates with the most votes will be safe and the remaining housemates will have to battle it out in a live eviction showdown.
Tune into CBB tonight (Friday 18 September) at 9pm on Channel 5.
