11:06PM: Queen Latifah introduces Mackelmore & Ryan Lewis, who perform their poignant song, "Same Love," featuring Mary Lambert, as 33 diverse couples tie the knot at the Grammys.

9:51PM: Following that incredible rap and rock collision, we take a little country music break with newcomer Kacey Musgraves. I wonder if she is saying to herself, "How do I follow that?"
9:45PM: Kendrick Lamar and Imagine Dragons join forces for an energetic mashup performance! Lots of censoring for this one... thanks to Lamar's rap. Lamar is going to have to take a nap after that performance. #TheGrammys tweets, "Social media has spoken! kendricklamar and imaginedragons is the performance of the night so far!"
9:35PM: Presenter Jamie Foxx is hilarious, talking about all the shenanigans backstage. Justin Timberlake and Jay-Z win Best Rap/Sung Collaboration for "Holy Grail." JT is not in attendance but Jay-Z accepts, telling daughter Blue Ivy, "Daddy's got you a gold sippy cup!"

8:32PM: Steve Coogan is at the Grammys? He isn't there to talk about his multi-Oscar nominated film "Philomena" because that would "tacky," but rather to introduce Katy Perry performing a creepy "Dark Horse" rendition with Juicy J. Ohhh, there's pyrotechnics, too!
8:29PM: Daft Punk wins Best Pop Duo/Group Performance for "Get Lucky." Pharrell Williams accepts the award because the other guys are dressed as robots.
8:25PM: Hunter Hayes debuts his new song "Invisible." Powerful.

8:07PM: Host LL Cool J hits the stage. "Music has the power to bring people together like no other... maybe not as together as Beyoncé and Jay Z, but..." He gives a powerful opening speech about how music has brought him here today, and then calls out many of the artists in the audience for how music brought them all there. He's Cool.
8:05PM: Hubby Jay Z joins Bey onstage, doing his rap thing. The two get very comfortable with each other. They are definitely the music biz's hottest couple.
8:00PM: The Grammys begin! Beyoncé opens the show, looking ultra sexy, silhouetted, sitting in a chair, singing "Drunken Love." She's being censored for her racy lyrics. Too bad.
