Taylor Swift's new music video wasn't the only thing worth looking at during last night's MTV Video Music Awards ... check out what was going down backstage.
Rappers were hanging out with pop stars ... Katy Perry was doing crazy costume changes and Ellen was posing for pics with EVERYBODY!
The award show itself didn't have any angry Kanye interruptions or Britney Spears dancing with a snake -- but there was still plenty of action behind the scenes at the moon man ceremony.
