The rivalry allegedly began more than two decades ago, which saw the 90s Britpop stars, Liam and Noel Gallagher from Oasis and Williams, exchange insults at each other, including a challenge made by the Rock DJ singer at the 2000 Brit Awards Ceremony to fight Liam Gallagher.

For Liam Gallagher, the masterplan was to crack a joke. And one fan spotted the singer, 52, putting his sense of humor on display while at their Oasis comeback tour. A concertgoer shared footage of Liam jokingly pretending to snort drugs backstage during the August 3 show at Wembley Stadium in London.

"I’ve just been told don’t do any of that shit anymore because you don’t know how to behave yourselves," singer said of fan skirmishes over his discarded instruments

OASIS wrapped up their two-night run in Croke Park with a star-studded after-party for 200 guests in famous Dublin traditional pub O’Donoghues – but there was no sign of Liam. Noel Gallagher

Oasis is currently on their first tour in over 15 years. The band, made of brothers Liam, 52, and Noel Gallagher, 58, was formed in 1991. After years of feuding amid a complex relationship, the band broke up in 2009 at the Rock en Seine festival near Paris following a fight between the brothers.
