Fans are slamming Adele after she cancelled her tour, but the pop star has a lot more to lose than a few fans - millions more.

The Hello hitmaker is expected to miss out on millions of dollars from her Wembley cancellations as the shows were to be filmed for a DVD.

According to The Sun, a crew had been set to man 100 cameras to record Adele Live 2017: The Finale, under the direction of Matt Askem, who directed concert videos for Take That and Muse.

The film would've centred around footage from the Saturday and Sunday nights of her four-date run at the stadium and was projected to be the most successful film of its kind.

However the singer cancelled the shows on Friday after damaging her vocal cords and was left unable to perform on her doctor's orders.

A source told The Sun "The DVD was a huge production and all the plans were in place for it to go ahead. But obviously that extra pressure must have been on her mind as her voice problem developed.

"It's a big disappointment, but nobody knows at this stage if it will happen again. Of course the DVD would have made millions in global sales."
