Katy Perry hosted this year's MTV Europe Awards // Katy Perry(Rex)

This year's MTV Europe Awards were certainly memorable, for many reasons. For the second year running, they were hosted by American singer Katy Perry, who managed to change into a staggering seven different outfits during the event. The ceremony was held in Berlin, to commemorate the 20th anniversary of the fall of the Berlin Wall.

The big winner of the night was Beyoncé, who managed to score three awards: Best Female, Best Single and Best Video, and rock legends U2 performed a special concert at the Brandenburg Gate to coincide with the special venue.
