Thousands score an accidental free Adele concert as she does her sound check

THE British superstar has finally arrived in Australia and some lucky fans were accidentally treated to a sneak peek of her concert.

ADELE singing ‘Hello from the outside’ became especially true when thousands of her fans were treated to an accidental concert in Perth.

The British powerhouse has finally arrived down under for her Australian leg of the tour and took the time to wow her Perth fans, without even realising it.

The singer performed a sound check at the city’s Domain Stadium on Sunday night ahead of her sold out Tuesday night show and fans living near the oval were thankful for it.

Does Adele has any idea that she's almost giving Perth free concert? 😂

The singer’s sound check could be easily heard from kilometres away and considering her actual concert is drawing more than 60,000 people to the Perth stadium tomorrow, many were thankful for the performance.

Adele’s concert is drawing the biggest crowd Domain Stadium has ever seen and the city’s public transport system is expected to experience its busiest night in history.

7 News in Perth obtained footage of the singer giving a performance of Hello worthy of her 15 Grammy Awards.

Adele also posted a timelapse video of the stage being set up writing, “See you tomorrow Perth X”.

The 28-year-old singer made a very low key entrance to Australia a week ago and is kicking off the down under leg of her tour in Perth on February 28 and will finish in Melbourne’s Etihad Stadium on March 19.

Adele is travelling with her son Angelo who she shares with husband Simon Konecki.

Considering nose bleed seats retail for more than $100 each, it wasn’t much of a surprise when The Sun recently revealed Adele’s world tour earns the singer close to $850,000 a night.

A source told The Sun: “Given this was Adele’s first ever world tour her earnings really are incredible.”

“Adele was selling out arena after arena every night so her income would definitely have shot up at the same rate throughout the rest of the year.

“It’s no wonder she was so keen to upgrade to stadiums for her upcoming Australia tour,” they added.
