Lady Gaga launched her 2025 Mayhem Ball tour at Las Vegas’ T-Mobile Arena on 16 July before a sold-out crowd, marking the pop star’s first U.S. arena trek since 2018. The run supports her Billboard 200-topping album “Mayhem,” which yielded the five-week No. 1 single “Die With a Smile.” The opening-night performance ran two hours and 12 minutes and featured a 28-song set that blended catalog hits such as “Poker Face,” “Just Dance” and “Bad Romance” with newer material. “Kill for Love,” from the Mayhem album, and the fan-favorite “LoveDrug” received their live debuts, while early track “Summerboy” appeared for the first time in 18 years. Gaga returned after the apparent finale to deliver an encore of “How Bad Do U Want Me.” The North American leg comprises multi-night arena stands in Las Vegas, San Francisco, Los Angeles, Seattle, New York, Miami, Toronto and Chicago, concluding 17 September. A European leg begins 30 September at London’s O2 Arena and is scheduled through 20 November.
