Adele fails to sell out Munich shows as fans fear singer will cancel upcoming European return tour

LAS VEGAS, NEVADA: Adele reportedly failed to sell out her homecoming shows in Europe after canceling the second part of her Las Vegas residency due to a health crisis.

The singer, 35, will perform for the first time since 2015 on ten concerts in Munich from August 2 to August 24.

However, The Sun reported that even with her enormous popularity, thousands of tickets remain on Ticketmaster for the 80,000 capacity shows.

Source claimed 'there is some fan reticence about buying the tickets'

The announcement that tickets for the Munich concerts are still unsold follows earlier reports that the exorbitant cost of the tickets was the reason they were not selling.

Following last month, when 260,000 fans waited hours in line for the best and cheapest seats, they grumbled about the 'vile' price of the tickets.

According to The Sun, the most expensive ticket, which was stage-side, was over £1,000, while the cheapest one was only £281.

A source told the outlet at the time: "If seats don’t sell, promoters might have to consider reducing prices. Hotel prices are through the roof. It's a mess."

Now, it has been reported that fans are afraid to spend a lot of money on tickets in case Adele has to postpone or cancel once more.

"There is some fan reticence about buying the tickets, because people are worried about whether Adele will be well enough to perform them all," an industry source told The Sun.

"People follow her extremely closely — and Adele has been silent for a couple of weeks since announcing she was ill and taking a break. So her followers are worried about her and when she will be back."

The source further added, "But Adele has access to the very best treatment for whatever she needs in California, and a strong team around her."

After finishing her residency in Las Vegas in June, Adele is scheduled to play 10 shows in Munich in August.

Adele canceled ten shows over five weekends in Las Vegas two weeks ago because of illness. The 'Hello' singer was rumored to be recovering in California, where she has been seeing doctors.

According to reports, Adele has also been cautioned about the possibility of long-term vocal harm as a result of her busy schedule.

Fans are awaiting a new date for the performances.

Adele postponed Las Vegas residency due to sickness

Adele revealed in February that she had been put on vocal rest, but only a few days later, she announced the devastating news that all 10 of her March gigs in Las Vegas will now take place at a later time due to her 'doctors orders' to rest.

In an Instagram statement on February 28, the Grammy winner expressed regret for the "inconvenience" and said: "Sadly I have to take a beat and pause my Vegas residency. I was sick at the end of last leg and all through the break."

"I hadn’t quite gotten the chance to get back to full health before shows resumed and now I’m sick again and unfortunately it’s taken a toll on my voice. And so on doctor’s orders I’ve had to rest thoroughly."

"The remaining five weekends of this leg are being postponed to a later date. We are already working out the details and you will be sent the information asap."

Several fans were upset that they would not be able to attend the rescheduled dates because they had already paid for hotels and plane tickets for the original dates.

Adele has not spoken since making her statement, which has many of her fans worried that they won't get to go on any more dates. Since she has only postponed the gigs rather than canceled them, fans won't be eligible for a refund.

She is estimated to be making about £1.5 million a concert, and her run at Caesars Palace's The Colosseum is scheduled to end in June, per Daily Mail.
