The singer will front a series of programmes on Magic 105.4 throughout December, including a special show on Christmas Day.
The string of shows began on Saturday, December 1 and will continue every Saturday from 1pm-3pm until Christmas Day.
"I can't wait to be back in the Magic 105.4 studio for a second year running, I actually asked for that, no-one asked if I wanted to do it, I was the one that put in the request," Bublé said.
"I was hoping I could do it again, I enjoy it so much. I would love to make it annual - you know for me to be part of tradition like that and to be invited into people's homes during the holiday that means so much, it's incredible!"
The star recently re-issued his multimillion-selling festive collection Christmas with a number of extra tracks.
