Adele: 6 golden moments from her tour

Adele has been touring for 14 months

Thousands of fans hoping to catch the finale of Adele's world tour are missing out after it came to an abrupt end at Wembley Stadium.

Wednesday's and Thursday's concerts unexpectedly drew the curtains on an epic global odyssey that has taken her to almost 50 cities in 20 different countries.

The "devastated" singer said on Friday night that she had sought medical advice after damaging her vocal cords and could not perform her final two gigs at Wembley on Saturday and Sunday evening.

The 29-year-old singer has been on the road since 29 February last year, performing one sold-out gig after another to her adoring legions of fans.

There have been plenty of memorable moments along the way - and plenty of bad language too. According to The Sun, her Wembley date earlier this week contained 56 swear words.

Here are six classic moments that ensured it wasn't just her vocals that her fans went home remembering.

1. The time she scolded a security guard

If Adele's fans want to stand up to watch her sing, they can damn well stand up.

It's a lesson one steward at Melbourne's Etihad Stadium learned to his cost in March this year for conduct that saw him get an ear-bashing from the main attraction.

"Excuse me sir, I know you work here but can you stop telling people to sit down?" she can be heard saying in one fan video.

"This is a music show," she continued. "If people can't see, then they can stand up."

2. The time she tore a strip out of celebrity magazines

While performing at the ANZ Stadium in Sydney, Adele found time to attack magazines for speculating about her private life.

Her diatribe, captured on Twitter, singled out "those terrible trashy gossip celebrity magazines".

"I can't even read them anymore because they're normally writing [nonsense] about me," she went on - using a slightly different word to nonsense. "I swear to God it's all lies."

The rant came just a few days after a concert in Brisbane in which she casually confirmed she had married her long-time partner Simon Konecki.

3. The time she freaked out over a mosquito

Brisbane was also the location for the memorable moment when Adele lost her cool over a rogue mosquito.

"There's a bug on me!" she was seen screaming in one YouTube video. "I'm sorry, I'm not Australian - I don't like bugs.

"It was sucking my blood!" the singer went on. "They're everywhere, they're all trying to kill me! Oh my god, how embarrassing."

Adele was in more forgiving mood while performing in New Zealand, enlisting the aid of an audience member to shoo some beetles off the stage.

4. The times she helped audience members propose

Marriage proposals were a regular occurrence during Adele's concerts, much to her delight.

It all began on her opening night in Belfast on 29 February last year, when she encouraged an audience member to accept a leap-year proposal from his female partner.

A few weeks later a fan proposed during one of her London concerts - a moment the singer called "the most beautiful thing I've ever witnessed at one of my shows".

In May last year, while performing in Copenhagen, Adele looked on as a fan proposed to his boyfriend. She then offered to be the surrogate mother of their children.

Further proposals followed in Zurich, Barcelona, Toronto and Melbourne, as documented by this article on Vulture.

5. The time she spoke about having another baby

Adele is usually tight-lipped about her private life off stage. On it, though, she can be an open book.

While performing in Nashville in October, for example, she was hilariously candid about her plans to give her son Angelo a sibling.

"My son is about to turn four very, very soon," she was quoted as saying. "I'm starting to get very emotional about it because I feel like once they turn four, they're not really your actual baby anymore.

"So my womb is starting to ache a little bit. It's like, 'Baby, baby, baby. Need a baby, need a baby.'"

But she immediately insisted she was not pregnant and had no plans to become so "until the end of the tour".

6. When she asked for Grenfell Tower donations

Adele's tour concludes at Wembley Stadium in London

Adele made the news again earlier this week by encouraging fans at Wembley Stadium to donate money to help those affected by the Grenfell Tower blaze.

"It's our job as human beings to be compassionate," she told the 98,000 present on Wednesday. "You'll be hearing a lot more from me about [Grenfell] in the days and weeks and probably years to come.

"They're not receiving the things we think they are," she said the following night. "No information is getting through, people feel helpless. It's chaos."

Her plea followed her attendance at a vigil for victims of the fire and the visit she made - with cake - to see firefighters at Chelsea Fire Station.
