Céline Dion left stunned by backstage fan proposal in Las Vegas

Céline Dion was at a fan meet-and-greet in Las Vegas, when one superfan took it a step further.

Nick Janevski decided to surprise his girlfriend Austin McMillan by getting down on one knee backstage at The Colosseum, at Caesars Palace – all as Céline Dion looked on in shock!

Austin, 24, posted a photo of herself accepting the proposal, with the stunned superstar singer in the background.

The bride-to-be took to Instagram afterwards to say, "Céline Dion is about the only person I wouldn't mind photobombing the pictures of our proposal"!

Austin, 24, told Entertainment Tonight, "Céline was shocked and I was too. She was super sweet and wished us a long and happy marriage like she had with her husband."

And the best part was, Austin revealed that Celine invited herself to the wedding!

We can't wait to see those pictures.
