Also discussing partners Victoria Pendleton and Sophie Ellis-Bextor, Brendan appeared to hint that his Strictly stint may be coming to an end.
He said: "15 series of Strictly Come Dancing, it's been euphoric, it's been tough, it is my life and I'm very, very proud to have been a part of every single second of it."
Fans took to Twitter in panic over the segment, saying that it felt like a "goodbye video", after Brendan had previously hinted he may not return next series.
One fan wrote: "Brendan still talking as if this is his last series?"
Another added: "Sounds like a goodbye speech, Brendan!"
A third emotionally tweeted: "That sounded like a goodbye to me. We want another 15 years!"
Brendan has hinted on more than one occasion of a possible exit after this series, particularly after his elimination with partner Charlotte Hawkins.
He wrote in a Best magazine column: "It was quite amusing that people took my comments when Charlotte and I were voted off as some kind of 'swansong'.
"I was obviously very emotional that night, but all I said was 'I've had one of the best years on this show in 15 years!
"And it's true. As for quitting Strictly next year or not, that's my decision - one which I will come to when I'm ready.
"I didn't allude to anything, or say anything one way or another."
