Singer couldn't believe what she was seeing

Before taking to the stage at her Las Vegas residency, Celine Dion likes to meet some of her fans in person.

However, it looks like one devotee may have been looking for some encouragement rather than an autograph after he proposed to his girlfriend in front of the singer.

The Canadian pop star was stunned as Nick Janevski asked his partner Austin McMillan to marry him backstage on Friday.

Fortunately for Nick, Austin said 'yes', prompting a thrilled Celine to invite herself to their wedding.
