Sources inside the Recording Academy say they expect at least one more announcement of Grammy performers before the 4/3 show in Vegas.

Conversations are said to be continuing with superstars Taylor Swift, Justin Bieber, Lady Gaga and Ye (fka Kanye West).

Other big name circulating include BTS, Olivia Rodrigo, Lil Nas X with Jack Harlow, Billie Eilish, Brothers Osborne, Brandi Carlile, Jon Batiste, H.E.R., Nas and Chris Stapleton, who'd join newly announced participants John Legend, Carrie Underwood, Silk Sonic, Aymée Nuviola, Billy Strings and J Balvin and María Becerra.

Saturday's highly rated NCAA games give CBS a big promotional opportunity to drum up viewership with some late-breaking superstar power.

Will Grammy roll out more major names by week's end? Stay tuned.
