Adele has listed a further two dates to her "The Finale" shows at Wembley Stadium next summer, less than two hours after tickets went on general sale for what could be her last performances for several years.
But the singer's fans were in uproar on social media today, as tickets for these final two dates sold out in seconds.
Last week, Adele announced two more chances for British fans to see her before she steps out of the spotlight, just hours after celebrating the last of a whopping 107 dates in the first 10 months of her Adele Live tour.
She will round off her tour, which continues in the new year with a handful of dates in February and March, with four surprise shows at Wembley Stadium in the summer: on Wednesday 28 June, Thursday 29 June, Saturday 1 July and Sunday 2 July.
When it was announced late last year that she would be touring, demand far outstripped supply for tickets, despite her playing 19 arena dates in the UK and two in Dublin. Many fans were left disappointed after website crashes, and tickets ended up on the secondary market for many times their face value.
With a capacity of 90,000, there are nearly five times as many tickets available for these new Wembley Stadium shows as there were for the O2 Arena concerts Adele played when she was last in the capital.
How can I buy tickets?
Tickets for the 28 June and 2 July shows went on general sale on Friday 9 December, at 10.00am GMT, but had already sold out from all three approved ticketing agencies within the first two minutes.
How much do tickets cost?
Tickets for her the Wembley shows released on Friday were priced between £49.50 and £104.50 - but by 10.05am, all three approved ticket retailers (See Tickets, Eventim and Ticketmaster) were completely sold out.
Despite warnings on the approved websites that these tickets were not for resale, tickets for her "Finale" concerts are already being listed on secondary retailer Viagogo for as much as £6,600 per ticket.
What happened in the pre-sale?
During Wednesday's pre-sale, Adele fans were left frustrated by online queues to buy tickets for what could be her last show for several years.
People who had signed up in advance to get early access were left "in line" for tickets within seconds of the sale opening on Wednesday morning – and were still in the queue an hour later.
Others, however, had more success and managed to buy tickets shortly after the sale began – to great jubilation:
Meanwhile, tickets swiftly appeared on re-sale sites within 20 minutes of the sale beginning, despite stern warnings from the promoter that re-sold tickets would be cancelled:
Tickets appeared for many multiples of their face value on secondary market website Viagogo on Wednesday morning, with tickets listed for thousands of pounds:
By 10.25am, fans trying to buy tickets were reporting that the Golden Circle section had sold out.
But there were rewards for the patient: many fans had waited more than 40 minutes and were still able to buy tickets, while others remained in the queue:
What can we expect?
Traditionally, Adele hasn't disappointed. The Tottenham singer matches verbal virtuosity with the best stage patter produced this side of the millennium, and has received five-star rave reviews around the world for a tour that makes her voice and personality the stars of the show.
Don't go expecting the high-tech gimmickry deployed by other arena artists – there are few costume changes, half-conceived concepts or showy stagecraft here – but if you love Adele, and her songs, you're bound to have a good time.
The singer has made the headlines throughout her tour for the way she talks to her fans and delivers different surprises every night: from allowing on-stage proposals to expressing her surprise at seeing an old friend in the crowd. Most recently, she was baffled by the presence of a bat in Mexico, but that is less likely to happen in west London.
Adele blew the critics away with her headline performance at Glastonbury this summer, where 150,000 people turned up to belt their way through Someone Like You together – as millions tuned in from home. There's a reason why these tickets sell like hotcakes.
Is this the last we'll see of Adele?
Possibly. The 28-year-old has made little secret of her ambitions to spend time with her partner and their son, and has been open about her desire to have another child. Tabloid reports claim that she may stay away for the stage for as long as a decade, although a Los Angeles residency may be on the horizon.
