Katy Perry, Taylor Swift to Perform at Grammy Nominations Concert

Katy Perry and Taylor Swift have been added to this year's Grammy Nominations Concert Live!! – Countdown to Music's Biggest Night, set to take place this Friday, December 6th, at 10 p.m. EST on CBS – though both will literally be phoning in their performances. Perry, who just released her fourth album Prism, will take the stage from Canada, while Swift's set will come all the way from Australia where she is currently on tour behind her 2012 effort Red.

Lorde, one of pop music's breakout stars this year, has also been added to the lineup, as have members of Earth, Wind and Fire and T.I., who will take the stage with previously announced performer Robin Thicke. R&B singer Miguel is also now set to perform alongside country superstar Keith Urban. Drake and Macklemore and Ryan Lewis are also among the previously named acts, and more presenters and performers could be announced shortly.

The show will be helmed by two-time Grammy emcee, LL Cool J – who has hosted the nominations special since it began in 2008 – while Arsenio Hall, Enrique Iglesias and Ed Sheeran are all set to appear as presenters.

The 56th Annual Grammy Awards take place in Los Angeles and will air live on CBS on January 26th, 2014, starting at 8 p.m. EST. Ahead of the big night, the Grammys will honor Carole King, who will receive the MusiCares 2014 Person of the Year award during a charity fundraiser on January 24th; the ceremony will feature performances from Lady Gaga, the Dixie Chicks, Steven Tyler, James Taylor, Bette Midler and Jason Mraz.
