Hosted once again by LL Cool J and broadcast live on CBS, stars in attendance included Adele, Justin Timberlake, Frank Ocean, Mumford & Sons, Katy Perry, Jay-Z and Beyonce.
Rihanna and Chris Brown, who recently confirmed that they are back together, each walked the red carpet separately. However, they sat next to each other at the ceremony.
Ed Sheeran, Carly Rae Jepsen, Carrie Underwood, Florence Welch, Kelly Rowland, Wiz Khalifa and a heavily pregnant Amber Rose were also among those who posed for photographers ahead of 'music's biggest night'.
