Five things to watch for at the Grammys

Las Vegas will host the Grammys for the first time ever Sunday, one year after the coronavirus pandemic forced organizers to shake up the broadcast with a cabaret-style show heavy on performances.

Music's most prestigious awards ceremony comes with the entertainment world on edge, just a week after a shocking twist at the Oscars that saw Will Smith slap Chris Rock onstage over a bad joke.

The incident is sure to prompt stiffer stage security and script vetting in Sin City, but there's always a little room at the Grammys for things to get... weird.

- Olivia Rodrigo sweep? -

 Two years after Billie Eilish cleaned up the "big four" prizes -- Album of the Year, Song of the Year, Record of the Year and Best New Artist -- viral pop sensation Olivia Rodrigo has the chance to do it again.

The former Disney channel actress -- who posted record-breaking streaming numbers last year during her explosive ascent to pop's upper echelons -- has a total of seven nominations, including in all four of the most prestigious categories.

Rodrigo, 19, is among a coterie of pop stars including Justin Bieber and Doja Cat leading this year's nomination pack.

The "drivers license" singer is also slated to perform, as are a variety of acts including BTS, Billie Eilish, Lil Nas X, H.E.R. and nominations frontrunner Jon Batiste.
