Katy is currently touring the world with the Lifetimes Tour. The singer had two sold-out dates in Mexico City, including April 26. Lady Gaga made a surprise announcement yesterday, revealing that she would be performing her long-awaited album ' MAYHEM ' on the same day, even before the release of the project.

Katy Perry and Lady Gaga just reignited the “Roar” vs. “Applause” debate that had lay dormant for more than a decade. The two musicians are playing shows in Mexico City on the same day. Fans in Mexico City have a choice to make: Katy Perry or Lady Gaga.

Lady Gaga will perform her first concert in Mexico in 13 years on April 26 at the GNP Seguros Stadium in Mexico City, Live Nation announced on Monday (March 3) in a press release, followed by a post by the pop star on Instagram.

The Lady Gaga phenomenon in Mexico mirrors the massive impact the singer has had over the years in the music industry and global pop culture.
