Gwen Stefani's own one-hour Christmas show was aired last night (December 12) on NBC. In the festive special the No Doubt star featured an Advent calendar which her mother had given her when she was 8 years old. 

On opening one of the windows Stefani was confronted by her old childhood bedroom where she met her younger self.

The 8-year-old told the 41-year-old Stefani that she was asking Santa Claus for a new Shaun Cassidy poster to replace the one her brother had torn up. Cassidy was a huge TV star in the '70s alongside his half-brother, the late David Cassidy.

The 'You Make It Feel Like Christmas' show featured Stefani's boyfriend, Blake Shelton, NE-YO, Chelsea Handler, Seth McFarlane and Ken Jeong.

In the show, Stefani sang Jingle Bells, Let It Snow, White Christmas and Santa Baby which all appear on the three-time Grammy award winner's new Christmas album, 'You Make It Feel Like Christmas' which was released on October 6.
