Olivia Rodrigo is set to host and perform as the musical guest on Saturday Night Live. However, there is some uncertainty about the timing, with some outlets suggesting it is happening immediately, while others imply it may be part of a larger lineup of hosts for the month of May, which also includes Matt Damon and Will Ferrell.
