Robin Thicke's 'Blurred Lines' just keeps going and going and going... Today, the singer was added to perform at the upcoming Grammy Awards show.

Thicke, who is up for three Grammys awards, will join the stage with the group Chicago. "Honored to announce I will be performing on @TheGRAMMYs Jan. 26th on @CBSTweet. Dream come true #GRAMMYs," said Robin on Twitter. Based upon his past appearances at the 2013 MTV Video Music Awards and the 2013 MTV Europe Music Awards, we'll most likely get a pop-rock version of 'Blurred Lines.' No word on whether Miley Cyrus will be joining him onstage.

Additional names added to the annual awards show gala today include Katy Perry, Lorde and Metallica.

One of the biggest names previously announced to bless the stage that night is Kendrick Lamar. The Compton rapper will perform a special track with hot rock band Imagine Dragons.

The 2014 Grammy Awards will take over CBS on Sunday, January 26th at 8:00pm ET.
