LL Cool J Talks Grammys After Whitney

What a difference a year brings.

PICS: Best Dressed at the Grammys

The 2012 Grammy Awards took on a somber mood, as the music business and the world grappled with the loss an icon -- Whitney Houston. LL Cool J, who hosted last year, returned to emcee the event on Sunday where he told ET's Nancy O'Dell and Rob Marciano how this year's event will differ.

"Last year was a different thing -- that was sad," said LL Cool J, who had to put in last minute rehearsals and change the tone of the night last year out of respect for Houston and her family. "This year it feels good because we're here to celebrate."

The night included performances by Bruno Mars, Miguel, Justin Timberlake and Jay-Z to name a few.

LL Cool J performed the show's finale with Travis Barker and Chuck D, but before he hit the stage, he performed his own rendition of Carly Rae Jepsen's Call Me Maybe -- the grown folks version.
