James 'Lockie' Lock, Tom Pearce, Lewis Bloor, Elliott Wright, Tommy Mallet and James 'Diags' Bennewith showed off their moves on stage at the end of last night's episode.
The charity gala was hosted by Bobby Norris, who organised the event to raise money for the Anthony Nolan charity following his mother's diagnosis with leukaemia.
After a raffle, the girls were wondering where the boys had all disappeared to, but Bobby assured them: "We're in for a bit of a treat. We've got a bit of a show going on."
Calling themselves the 'Hot Spices', the boys walked out on stage in waistcoats, trousers and hats before starting their Full Monty-themed sequence.
Dan Osborne, who had helped the boys with their routine, didn't take part but he was walking around in his underwear collecting money while the strip show began.
Performing a strip tease to Donna Summer's 'Hot Stuff', the boys gradually whipped off their clothes, much to the shock and surprise of the girls!
Once they got to their boxers, Georgia Kousoulou even shouted at her boyfriend Tommy: "Put that away!"
Meanwhile, Danielle Armstrong was seen yelling over at her boyfriend Lockie: "You leave them on James, leave them on!"
When the boys made the final move and whipped off their boxers, the girls pretty much went crazy with screams and cheers... and poor Lockie did his best to keep his boxers on, but the boys were adamant to rip it off!
And eventually, all the boys were left with just their hands protecting their modesty...
We reckon it went down a storm though, as the stars were seen whipping out their phones to record the dance.
Fran Parman looked to be in tears of laughter and Nanny Pat was seen clapping along, although Vas J Morgan looked like he was about to throw up!
After the hilarious scenes, Lockie tweeted: "We will be releasing tour dates for the #HotSpices soon!! Coming to a town near you!! #TOWIE."
He added this morning: "Good morning! Hope everyone enjoyed last night's series finale of #TOWIE, roll on the next series!!"
TOWIE will return with a Christmas special in December.
