Fans were left devastated this morning after Ariana Grande's One Love Manchester concert tickets sold out in just six minutes. The huge gig will feature a star-studded line up, including Little Mix, Justin Bieber, Katy Perry, Miley Cyrus, Niall Horan, Pharrell, Usher, Take That and Robbie Williams - to name but a few.

Site crashes, error screens and sold out messages sent people into a frenzy, and many then accepted that they may just not be able to attend the concert.

The tickets were only available from Ticketmaster, which had vowed to ban tickets from being sold on secondary sites for an increased price. Some, however, slipped through the net and have appeared on sites like eBay, for more than ten times the original price of £40.

People have been left shocked, angered and saddened at the revelation.

While it's unclear if the people selling them planned to donate the money to charity themselves, the ticket price had been decided by the artist and organisers for a reason. Ariana wants her fans to have the tickets, not someone who plans to sell them on, whatever price.

eBay is doing all it can to deter the behaviour, and has now deleted most, if not all of the listings. A spokesperson said,

All tickets for this event will most certainly be removed by the team who are doing manual sweeps to pick up any that slip through.

We also aren't allowing the sale of ANY item which profits in any way from the tragedy in Manchester. All of these items are being removed if they appear.

Customers can give at checkout to the Manchester fund via the Red Cross.

They also tweeted to warn people of the consequences.

Anyone who uses a great cause like this to make a profit really are the lowest of the low.

Unfortunately, that wasn't the only controversy surrounding One Love Manchester today. 14,200 free tickets had been reserved in advance for those at last week's Ariana Grande concert, but Ticketmaster revealed that more than 25,000 applications had been received to attend Sunday's gig for free.

"Sadly, over 10,000 unscrupulous applications have been made," said a spokesperson for the ticketing company.

"At Ticketmaster we are doing everything we can - including extending today's deadline - to ensure that tickets go to the actual fans and not the opportunists or touts who have also been applying for free tickets."

If you didn't manage to get tickets, you can tune into the television coverage on BBC One, from 6.55pm until 10pm.
