Lady Gaga, 30 Seconds To Mars, Tokio Hotel Take Home O Music Awards

Chiddy's record-breaking rap and performances from Lupe Fiasco and Matt and Kim light up Las Vegas.

On Thursday night (April 28), MTV's first-ever O Music Awards took over Las Vegas. With performances and award presentations streamed from all over the world, the digital awards show recognized "about every gigabyte of music activity known to man," according to hosts (and rock duo) Matt and Kim.

The pair hosted the show from Vegas' famed Fremont Street and kicked off the O Music Awards with a two-song set before introducing Cee Lo Green, who logged online to present the Most Innovative Artist Award to Lady Gaga.

Gaga, who, according to Cee Lo, did "the best job saying 'f--- you' to rules," graciously accepted the O cube along with the award for Must Follow Artist on Twitter and told her following, "To all the monsters watching, surge on."

Chiddy Bang's Chidera "Chiddy" Anamege used the O Music Awards as a platform to successfully beat the nine hour and 16 minute "Longest Freestyle Rap" Guinness World Record with a time of nine hours, 18 minutes and 22 seconds. He celebrated the feat by debuting his brand-new single "No One Like Me" to the Vegas crowd, complete with Mr. T, Kiss, Bret Michaels and Pee-wee Herman impersonators.

Performances by Lupe Fiasco and Foster the People were neatly laced into the awards show, but the topper was Mumford & Sons, along with Edward Sharpe and the Magnetic Zeros and Old Crow Medicine Show's Austin, Texas, hoedown.

Although he wasn't nominated for any awards, Justin Bieber inadvertently became a star of the show when Lil B's "Justin Bieber" video was shown, pumping up fans for the Best NSFW Video Award that went to 30 Seconds to Mars' "Hurricane." Accepting the award in a bathroom (as they are currently on tour), Jared Leto seemed genuinely excited and thanked fans for the support.

Alex Goot, who won Best Fan Cover Award for his rendition of Britney Spears "Hold It Against Me," followed up his win by singing a sweet and softly sung cover of "Don't Let Me Fall" by B.o.B.

Obviously no online awards show would be complete without the presence of pop-culture wunderkind Rebecca Black, who started her weekend early by "holding it down" at the Golden Nugget Hotel and Casino to host the Fan Army Party. Encouraging viewers to vote for their Favorite Fan Army, it was the last award of the night and went to Tokio Hotel's Humanoids.
