Loved up Taylor Swift rules the Billboard Music Awards, Kanye West gets booed

One Direction and Taylor Swift were the big winners at the Billboard Music Awards in Las Vegas.

Hosted by model Chrissy Teigen and Ludacris, performers included Kanye West, Iggy Azalea and Britney Spears.

The awards show as it happened:

Introduced by his sisters in law Kendall and Kylie Jenner, Kanye West closes the Billboard Music Awards with a fiery performance.

He was booed after Kylie introduced him as "a doctor" after West earned an honourary doctorate from the Art Institute of Chicago.

Kanye West is closing the #BBMAs somewhere behind all those pyrotechnics. You'll just have to take our word for it.
