Justin Bieber and Carly Rae Jepsen were among a number of artists to give crowd-pleasing performances at last night's Teen Choice Awards 2012 in Los Angeles.
The 'Never Say Never' star gave one of the stand out performances of the night when he took to the stage at the Gibson Amphitheatre for renditions of his recent hit 'Boyfriend' and new single 'As Long As You Love Me'.
Justin stepped out in a metallic themed waistcoat and trousers, along with bronze armour plating down his left arm, while backed by a group of dancers to kick off his 'Boyfriend' performance.
The Canadian pop singer was then joined by collaborator Big Sean for his song 'As Long As You Love Me', after being raised up above the crowd on a platform.
