Teen Choice Awards 2015: Britney Spears, Little Mix And The Janoskians Hit Red Carpet, But Who Were Best And Worst Dressed? (PICS)

The stars came out in force for the Teen Choice Awards on Sunday night, with a host of the biggest celebrities from all sections of the entertainment industry throwing on their finery and hitting the red carpet.

Britney Spears was one of the most talked-about stars of the evening, debuting some rainbow-coloured, dip-dye hair for the evening, where she took home the surfboard for Style Icon.

‘X Factor’-winning girl group Little Mix also managed to turn heads on their arrival, by showing up to the awards bash in the geek-inspired outfits we last saw them wearing in the music video for their chart-topping single ‘Black Magic’.

However, they later changed out of their sweater vests and faux glasses and into something a little more red carpet-friendly, posing together after the event.

It wasn’t just the ladies who were dressed to impress, though.

‘Empire’ actor Bryshere Y Gray, Jason DeRulo and Josh Hutcherson were among the men who made an impression on us on the red carpet, though they paled in comparison next to The Janoskians.

The Australian YouTube comedy troupe managed to cause an impression by hitting the red carpet in this attire.

It might seem like they’ve come in their glad-rags, but get a closer look and you’ll notice they’re actually sporting coloured body paint, which we’re sure their fans will just love...
