EW's editorial guidelines Published on April 26, 2017 04:02PM EDT Photo: Taylor Hill/FilmMagic; Frazer Harrison/Getty Images SNL is finalizing plans for the end of its 42nd season, announcing Wednesday via Twitter that Haim and Katy Perry will be the final musical guests, performing, respectively, on May 13 and May 20. Haim will join host, and Sean Spicer-impersonator, Melissa McCarthy for the Emmy-winning, Oscar-nominated actress' fifth time hosting the late-night show in less than six years. Perry will perform a week later on the season finale, hosted by Dwayne Johnson. Four years after the release of their last single, the Haim sisters were back teasing new music last week with a short trailer featuring Danielle bashing on some drums in a recording booth. The band also shared the SNL news and their excitement on Twitter, saying, "WE'RE PLAYING SNL AGAIN HOLY S—." Perry also seems set to release new music after the success of her single "Chained to the Rhythm" in February. The singer has been frequently using a cherry pie emoji as of late, apparently alluding to an upcoming project. It was previously announced that LCD Soundsystem will appear on the May 6 episode hosted by Chris Pine. All three episodes will air live across the country at 11:30 p.m. ET, 10:30 p.m. CT, 9:30 p.m. MT, and 8:30 PT on NBC.
