It's Britney! Britney Spears got the Billboard Music Awards off to a blistering and very, very sexy start on Sunday night

It was almost immediately apparent why the star was being awarded the night's biggest honour, the Millennium Award, as she gave fans exactly what they asked for and more.

As she stepped out onto the stage as the night's first live performance, initially the superstar looked a little nervous.

Clad in a circus-inspired sequined ensemble complete with top hat and over-the-knee boots, the singer kicked off her greatest hits medley on a raised platform.

Opening with her 2013 hit Work B***h, at first Britney seemed a little in her own head as she did the complicated dance moves.

Adding to the look's sexiness, there was a matching bedazzled choker and strings of beads that fell across her stomach.

While the sequins glistening, it was the singer's body which stole the show and shined the brightest.
