Justin Bieber and Taylor Swift have dominated the MTV Europe Music Awards, while South Korean internet phenomenon Psy took the coveted Best Video prize.
Swift was named Best Female Act and Best Live Act as well as picking up the prize for Best Look.
As she picked up the gongs, Swift said: "I am so excited I can't believe you gave me three awards. I'm kind of insecure in general - so this is great for my self-confidence".
Rita Ora kicked off this year's EMAs in Frankfurt, Germany, in spectacular style.
The British singer, who only released her debut album earlier this year, was lowered to the stage suspended in a cage before launching into a version of R.I.P.
She was followed by US pop band Fun who played their massive hit We Are Young, before Carly Rae Jepson performed Call Me Maybe.
The event was hosted by supermodel Heidi Klum and had a circus theme with trapeze artists and fire dancers joining the acts on stage.
Next up was Alicia Keys who performed Girl On Fire, before reality star Kim Kardashian presented the Best Song award to Jepson for Call Me Maybe.

Boyband One Direction won Best New Act, before Keys picked up the Global Icon Award on behalf of the family of the late Whitney Houston and praised the singer's "incredible ability to captivate and mesmerise us".
She told the audience Houston "was my home girl, my friend" before introducing a tribute video which included messages from One Direction and Lady Gaga.
Bieber won another award when he was named Best Pop Act, before Linkin Park won Best Rock Act.
