Rihanna, Justin Timberlake, Frank Ocean Rule Twitter At Grammys

From Rihanna and Chris Brown's Grammy date night to Wiz Khalifa's performance with Miguel, the stars got some serious attention from the Twitterverse on Sunday night. Fans cooked up new hashtags and took over the Internet to sound off on red-carpet fashion and the award-winners.

While Fun. took home Best New Artist and Mumford & Sons claimed Album of the Year, who won Twitter? MTV News rounds up the top five #GRAMMYs social stars of Sunday evening!

Rihanna Dressed The Best
The moment she stepped on the red carpet in a sheer, red Alaia dress, the Internet began to chatter. Simultaneously, 'Damn Rihanna,' 'Ri Ri' and 'Pon De Replay' trended on Twitter as we were reminded of the long 'do she rocked years ago. Once everyone got inside Staples Center, the camera locked in on her smiling and cuddled up with Chris Brown. Chris and Rihanna began trending and the tweets were positive about how cute the two looked together. And on MTV's Facebook poll, fans named her the best dressed!

Wiz Khalifa's Remix Comes Alive
When the rapper and Amber Rose announced they were due in three weeks, the couple began to trend. But Wiz got some more attention when he stepped onstage with Miguel to perform his remix of 'Adorn.' Their two names trended together with the song's name.

Justin Timberlake Is Back
Fans wanted #MoreJT after his big-band, sepia-toned 'Suit & Tie' performance with Jay-Z. And well after the show has ended, his song's title continued to trend.

The People's Choice
After losing to Fun. for Song of the Year, fan-made #EdIsOurWinner caught on and began trending. Though he may not have left with an award, Ed Sheeran got to perform with Sir Elton John and that's pretty honorable.

Frank Ocean Runs Ahead
Before the event even began, the breakout artist made an entrance by getting nominated for six awards. After winning for Urban Contemporary Album, the singer got some serious social love. And while many were confused by his 'Forrest Gump' running performance, Ocean's Twitter support re-emerged.

Honorable Mention: Justin Bieber
Though Biebs wasn't part of the show, fans went crazy when the singer's live stream didn't work. Followers offered tech support with homemade hashtags of advice. To keep the Beliebers happy, he decided to share a brand-new song with them.

Not-So Honorable Mention: Rhianna and Katie Perry
Uh, who? Two of the world's biggest pop stars had their names trend with the wrong spelling. Fail, Internet. Fail.
