The 16-year-old pop sensation received the coveted Artist of the Year trophy, beating artists such as Lady Gaga, Katy Perry and Eminem and making him the youngest artist ever to do so.
The handsome singer was also honoured with T-Mobile Breakthrough Artist of the Year, Favourite Male Pop/Rock artist, and Favourite Album for My World 2.0.
When receiving the Artist of the Year trophy, a thrilled Justin invited Usher to the stage, as the R&B sensation famously helped launch Justins career. The teen pop sensation called Usher "not only my mentor but my best friend and my big brother".

Rihanna opened the awards with a medley of her hits such as Love the Way You Lie (Part 2), What's My Name and Only Girl (In the World).
