The rock world’s favorite potty-mouthed siblings are at their bickering again: Liam Gallagher stormed off stage during last night’s Oasis show in Italy.

After Liam left during “Champagne Supernova,” brother Noel took the helm and played some perennial Oasis classics like “Little by Little” and “Don’t Look Back in Anger.” Let’s hope Liam takes the advice of his own band’s lyrics and looks back on this with some combination of embarrassment and regret for his diva ways. Oasis will be coming to the US for a slew of tour dates to support their recent release, Don’t Believe the Truth. For a full list of North American dates, click here.
