Justin Bieber brought his swag when he performed his single 'Boyfriend' on 'The Tonight Show With Jay Leno' on Wednesday night (June 27).

The 18-year-old was surrounded by backup dancers as he offered a high-energy rendition of his ultra smooth hit, which spent 13 weeks on Billboard's Hot 100 chart. He sported a denim jacket, leather pants and fingerless gloves as he bounced around the stage.

This week, Bieber made headlines with his latest album, 'Believe,' scoring the highest debut of the year. The LP was No. 1 on the charts this week in 30 countries. Meanwhile, the Canadian star also made history again by having four hit singles in the Top 40 on the Billboard Hot 100 -- 'Boyfriend,' 'All Around the World' featuring Ludacris, 'Die In Your Arms' and 'As Long As You Love Me' featuring Big Sean.

Bieber has been in full promotion mode since the release of 'Believe.' NBC aired a two-night Biebs special on June 20 and 21, while the Canadian star chatted with Jimmy Fallon via YouTube on June 21. In addition to 'Leno,' the teen sensation stopped by MTV on June 19, and 'Late Show With David Letterman,' '106 & Park' and 'The View' on June 20.
