Some of the world's top singers, musicians and recording artists are celebrating the past year in popular music tonight at the 56th annual Grammy Awards.

Chart-topping nominees — including Jay Z, Justin Timberlake, Macklemore and Ryan Lewis, Lorde, Kacey Musgraves and Kendrick Lamar — are attending the performance-packed gala.

The Grammys are administered by the U.S. Recording Academy. More than 70 awards were handed out at an earlier, pre-telecast ceremony, hosted by Cyndi Lauper.

The Grammy broadcast is taking place at the Staples Center in Los Angeles, hosted by performer LL Cool J and airing on CBS and Citytv.
