The lineup for Friday night's CBS special announcing the Grammy nominations just got a lot more star-studded.

Katy Perry will be seen performing in Canada, while Taylor Swift will be shown performing in Australia when The Grammy Nominations Concert Live! — Countdown to Music's Biggest Night airs Friday at 10 p.m. ET. In addition, Lorde will perform, and members of legendary R&B group Earth, Wind & Fire will join the previously announced Robin Thicke for his segment.  Also, R&B star Miguel will team with Keith Urbanfor a special performance.

In addition, Enrique Iglesias and Ed Sheeran have been added as presenters to the special which is hosted by LL Cool J.  A handful of Grammy nominations in top categories, like Album, Record and Song of the Year, will be announced during the show. 

It's a safe bet to assume that many, if not all, of the artists appearing have been nominated for something.  Taylor Swift, Lorde and Robin Thicke in particular are likely to hear their names called Friday night.
