The celebrity chef has been a constant on the Channel 4 series since it's conception back in 2010, but tonight saw the normally stoic judge confess that he was struggling to hold it together.
As the three remaining contestants lined up ready for the winner's announcement, emotions ran high before presenter Sandi Toksvig finally revealed that former Army officer Sophie was the triumphant baker.
Speaking directly to the camera away from the group, Paul, 51, admitted: "Can I be honest? I got a little bit emotional there because I saw Sandi about to cry and that made me emotional.
"I had to walk off quite quickly and I just went, 'Oh it's the wind, it's the wind in my eye'," he added before wiping his hand across his face.

The master-baker praised the 34-year-old when he said: "I'm made up for her. It's been a real learning curve for Sophie, to come up with that Entremet on the final day.
"I was really shocked about the standard."
Shaken from her surprise win, Sophie struggled to process the enormity of her success.
"Baking I thought was always just a calling," she said. "So to go from that initial idea, that almost sort of, inspiration, I never dared think about it until we were here. I've met some brilliant people, got to the final and now I'm here.

"It's beyond anything I could have thought or dreamed of. What a privilege, but yeah, it's pretty mega," she added.
South African judge Prue Leith also expressed her happiness for the winner, saying: "Sophie seems very calm but she's not that confident. Possibly because she knows everybody else has more experience than she has. I'm so proud of her. I'm really proud of all of them."
