Katy, 36, has been blonde for quite some time, but she decided to go over to the dark side for the starry event and we're loving the new look. It's not yet known whether a wig was used to create the colour switch-up or whether this is more of a permanent change, but regardless, Katy looked incredible while rocking an Amy Winehouse-style beehive, and a side-sweeping fringe.

The 44-year-old Lord Of The Rings star sported a freshly shaven face and had his brunette hair slicked back.

The event was packed with the biggest stars - and one of which was singer songwriter and actress Lady Gaga. Katy Perry got to show off her new hairdo to her friend Lady Gaga.
