After performing at the 2015 Super Bowl half-time show, “Dark Horse” hitmaker Katy Perry is among the artists who will headline the Brazilian seven-day music festival “Rock In Rio,” which will take place on Sept. 18-20 and 24-27 in Rio de Janeiro.

Aside from Perry, “All Of Me” hitmaker John Legend, Slipknot, Faith No More, System Of A Down and Queens Of The Stone Age will also perform at the “Rock In Rio” music festival, which will also have its North American offshoot festival in May in Las Vegas.

Currently, Perry is filming a sequel to the documentary “Part of Me.” Despite collaborating with Snoop Dogg on her song “California Gurls,” she recently revealed that the NFL banned her from allowing the rapper to take part in her 2015 Super Bowl half-time show. This is because of the offensive comments the rapper made against Iggy Azalea on Instagram.

Meanwhile, Perry’s 2014 hit song “Dark Horse” music video ranked fourth as the most viewed video of all time on YouTube, which celebrated its 10^th anniversary on Feb. 14. Posted on Feb. 20, 2014, the video has been viewed more than 825 million times with more than 2.5 million likes and more than 426,000 thumbs down. Watch the video here:
