Saturday Night Live is closing out its 40th season in a big way. They have lined up their guest performers for the last three episodes of the season and they include the likes of Wiz Khalifa, Florence and the Machine and Rihanna.

On May 9, Reese Witherspoon will serve as host of the show, while Florence Welch and company hit the stage to perform songs from the upcoming album How Big How Blue How Beautiful (even if still on that broken foot suffered from Coachella). The following weekend, Rihanna will bring her “American Oxygen” to SNL as Louis C.K. hosts the season finale.

Expect some memorable performances from both, who have plenty of material on the table to satisfy fans. Maybe we even hear something new from each?
