2013 MTV Video Music Awards: Best & Worst Moments

Starting the festivities was Lady Gaga who donned wigs and ensembles representing various Gaga eras during her "Applause" performance, getting everyone in the crowd like Will Smith and daughter Willow Smith moving and grooving. In typical fashion, Gaga topped herself by almost going topless: stripping down to a seashell bikini to watch the rest of the show.

After that came everything from Miley Cyrus stripping down to a yellow two piece while performing (and bumping and grinding) "Blurred Lines" with Robin Thicke to what appeared to be Kanye West having a seizure while performing. A performance that Thicke clearly approved of as he tweeted Kanye praise.

And not to mention, Selena Gomez and Taylor Swift  rocking out during Miley’s performance, which included performers Miley brought along from her favorite Los Angeles club, Beachers Madhouse? Because that happened too.

Held in Brooklyn at the newly opened Barclays Center, the biggest moment however, had to be without question, ‘N Sync’s reunion during Justin Timberlake’s performance!

Justin was performing a medley of his hits, which had Selena and Taylor, along with the rest of the audience on their feet. But what really made the audience freak was when all the members of ‘N Sync interrupted to perform a medley of their own hits on stage.

And that wasn’t the last of the fantastic surprise star turns. Macklemore & Ryan Lewis’ "Same Love" performance included a surprise appearance by Jennifer Hudson and might have been the most moving VMA performance to date! As for the most awkward moment, aside from Miley’s hair, did Taylor really drop an F-bomb while One Direction and ex Harry Styles were on stage?! The Internet sure thinks so.

And another awkward moment for the ex couple? While accepting the Moonman for Best Female Video for "I Knew You Were Trouble" Taylor said thanks to "who I wrote this song about cause you know who you are and now I have this award," while MTV then cut to a smirking Harry, who kept chewing his gum.

And speaking of One Direction, the band may have won Best Song of the Summer against Miley, Calvin Harris & Ellie Goulding, Daft Punk, and Robin Thicke, but when they went up to receive the award, the audience booed the boys! Faring far better with the crowd was Katy Perry, who closed out the show with a live performance of her hit single "Roar" outside under the Brooklyn Bridge.
