The result means that Louise Cliffe, Alex Rose, Jay Mckray and Aaron Allard Morgan have made it through to tomorrow (Friday) night's live final.
After Brian Dowling read out the results, Alex broke down in tears. Tom said to her: "Don't be upset, babes."
He added to Alex: "Make sure you win it for me."
Tom received a very positive reaction after he left the house from the crowd outside.
The Big Brother final will air on Channel 5 tomorrow night from 9pm.
