Saturday Night Live has confirmed that tonight’s show, featuring Paul Rudd as host and Charlie XCX as the musical guest, will have a limited cast and no live audience due to the COVID-19 Omicron variant rapidly spreading in New York City.
“The show continues to follow all government safety guidelines in addition to a rigorous testing protocol,” added a spokesperson for the series.
The news of SNL returning to the more rigid safety measures of only a few months ago shows the alarming speed that the new virus mutation is gaining across the country. Yesterday, for example, New York recorded its highest single-day cases of COVID-19 since the start of the pandemic.
