British singer Lily Allen has announced a North American arena tour scheduled for this fall. The news was reported by Pitchfork, which described the artist as the 'West End Girl' making her return to the United States. The announcement confirms arena-sized venues across North America but does not yet list specific dates or cities in the primary source. This development fits the observed pattern of mid-2000s pop artists resuming large-scale live performances in the U.S. after periods of reduced touring activity.
