Just after winning the award for international male solo artist, Bruno Mars celebrated by taking London's O2 Arena stage to sing "Treasure" at the BRIT Awards on Wednesday.

Rather than wearing anything similar to his Super Bowl halftime look -- a sleek gold YSL blazer and his signature hairsprayed hairdo -- Mars and his Hooligans band went casual to perform their latest hit. Mars wore a black leather jacket, cap and lace-ups, but added a few well-harmonized vocal interludes to the song bridge, while reprising the song's vintage-style choreography.

Beyonce, Katy Perry, Pharrell Williams, Lorde and Disclosure, Ellie Goulding, Bastille, Arctic Monkeys and Rudimental were also confirmed to perform at the O2 Arena stage.
