Justin Timberlake takes home the trophy for Video of the Year at the 2013 MTV Video Music Awards.

NEW YORK, NEW YORK, UNITED STATES (AUGUST 25, 2013) (MTV) -  Justin Timberlake won big on Sunday (August 25) at MTV's annual Video Music Awards, taking home the top prize for video of the year for "Mirrors" and a special achievement honor, and also led a much-anticipated onstage reunion of the boy band 'N Sync.

But even top VMA nominees had been overshadowed in recent days by the rumored 'N Sync reunion, their first performance since 2002, which took place in the midst of Timberlake's lengthy medley of hits ahead of his accepting the Michael Jackson Video Vanguard Award.

The singer noted that half of the many VMAs he had won were "with these four guys right here," referring to 'N Sync singers JC Chasez, Lance Bass, Joey Fatone andChris Kirkpatrick.

"I'm going to share - we can keep it at my house, but I'm going to share this award with them," Timberlake joked.

British sensation group One Direction, who won three VMAs last year, presented the night's first award - for best pop video, to Selena Gomez for "Come & Get It."Bruno Mars won best male video for "Locked Out of Heaven."

One Direction won another award this year, the fan-voted song of the summer, for "Best Song Ever."

Taylor Swift, who watched the show alongside friend Selena Gomez, won best female video for "I Knew You Were Trouble."

She cheekily thanked the inspiration for the song, about love gone wrong, saying: "I also want to thank the person who inspired this song who knows exactly who he is, because now I've got one of these."

In 2009 Swift became the topic of conversation after Kanye West famously interrupted her speech as she accepted an award. This year Swift is grabbing headlines on her own after cameras caught her allegedly mouthing a cuss word to Gomez as her ex-boyfriend Harry Styles presented an award with his group One Direction.

Macklemore, who won for best hip-hop video along with partner Ryan Lewis for "Can't Hold Us," said: "They let some independent hip-hop artists up here at the VMAs." The video, which featured Ray Dalton, won over top hip-hop performers such as Drake and Kendrick Lamar.

Later he injected a rare political note while accepting the prize for best video with a social message, for "Same Love."

"I'm going to be honest. I really wanted to win the best rap video. But this Moonman right here stands for a lot more," said Macklemore.

Other winners, some of whom were announced during a pre-show ahead of the live broadcast, included Thirty Seconds to Mars' "Up In the Air," which won best rock video, and Pink featuring Nate Ruess' "Just Give Me a Reason," for best collaboration.

Professional, or technical, winners included Bruno Mars' "Treasure" for best choreography and Macklemore & Ryan Lewis, whose "Can't Hold Us" took the prize for best cinematography.

Timberlake's videos picked up two other honors, with "Suit & Tie" winning best direction and "Mirrors" taking the editing prize. Timberlake and Macklemore & Ryan Lewis had led the nominations with six each.

New categories this year were song of the summer and artist to watch, both chosen by fans during the telecast. Austin Mahone won artist to watch.
