Adele takes extreme measures costing £400,000 to protect her voice during her Las Vegas residency

"Rumour Has It" Adele will reportedly be using technology worth £400,000 to protect her voice during her Las Vegas residency.

The 34-year-old, who postponed her Weekends with Adele at The Colosseum at Caesars Palace in January just 24 hours before the opening night, is set to finally take to this stage tomorrow night.

And the Sin City venue has pulled out all the stops, revealing its installed a "complex" system which will guarantee the pop star the "best possible air" while she sings.

A source told The Mirror: "They've had complex systems installed before, but this one really is on another level.

"The system works by combining dehumidifiers, purification units, water molecule dispersal and cooling fans in the preparation room and then guiding that air around the stage when she performs. Adele is getting the best possible air to protect her voice."

The Grammy Award-winning songstress previously had to undergo surgery on her vocal cords in 2011 after suffering a haemorrhage on them.
