London:
Someone Like You hitmaker Adele picked up 12 awards, including the coveted Top Artist prize, and dance act LMFAO went home with six gongs.
Katy Perry - who was accompanied to the event by her 91-year-old grandmother - said she felt "incredibly honoured" as she picked up the Spotlight Award in recognition of tying the record set by Michael Jackson of five number one hits from the same album, Teenage Dream.
She added: "Most of all, of course, I always say that the people have the power, so I want to say thank you to the glittering, gorgeous community of fans out there."
Taylor Swift was named Billboard Woman of the Year, with Lil' Wayne receiving the respective male honour, though he was not present at the ceremony - which took place at the MGM Grand Garden Arena in Las Vegas - to pick up the prize.
