Liam Gallagher has shrugged off criticism over the Oasis ticket sale fiasco in a series of tweets – including telling one fan to “shut up” and another to buy “kneeling tickets”.

The singer broke his social media silence shortly after the competition watchdog announced it had launched an investigation into Ticketmaster’s handling of sales for the band’s forthcoming tour, including how “dynamic pricing” may have been used to adjust the price.

Initial excitement about the Gallagher brothers’ reconciliation soon gave way to dismay and outrage last weekend after fans complained that the prices for the 17 shows were increased without warning.

Fans said they queued online for hours only to find that the price of the £135 standing tickets had risen to £355.

On Friday morning, Liam posted on X: “OASIS are back your welcome and I hear there ATTITUDE STINKS good to know something’s never change.”

When fans responded by criticising the ticketing approach, including one X user who said he “didn’t expect [Oasis] to rip off the fans as much as they have done”, Gallagher replied: “SHUTUP”.

And when asked how he was feeling, the 51-year-old responded: “SMUG only kidding SMUG AS F*** I told you all we were gonna get back together 1 fine day.”

Liam was also asked how his mother, Peggy, felt about him and Noel reuniting 15 years after the band split. “She’s gutted she couldn’t get a ticket,” he said. When one person questioned why he didn’t give her a free ticket, he said: “Free don’t be silly.”

Another fan asked the Mancunian if he had any “spare tickets”, to which he replied: “Shit loads but there really expensive 100 thousand pounds Kneeling only.”

In a statement, the band have previously said they had not known dynamic pricing would be used in the sale.

“Inevitably interest in this tour is so overwhelming that it’s impossible to schedule enough shows to fulfil public demand,” they said. “As for the well-reported complaints many buyers had over the operation of Ticketmaster’s dynamic ticketing: it needs to be made clear that Oasis leave decisions on ticketing and pricing entirely to their promoters and management, and at no time had any awareness that dynamic pricing was going to be used.”

Earlier this week, Liam was announced as the new face of the fashion brand Stone Island, fronting its autumn and winter campaign.

Around the same time, amid fan frustration over the ticket pricing, one of the frontman’s old tweets from 2017 resurfaced, in which he criticised his brother for expensive tickets for his US tour.

At the time he wrote: “350 dollars to go and see rkid in USA what a c*** when will it all stop as you were LG x.”
