British boy band One Direction have scooped three top prizes at the MTV Video Music Awards, confirming their stellar rise on the US music scene, while Rihanna won Video of the Year.
Rihanna's ex, Chris Brown, and edgy British singer M.I.A. were runners-up with two gongs apiece at the Los Angeles awards show on Thursday.
Barbados-born Rihanna, who went into the evening with the most nominations at five along with rapper Drake, opened the show with a high-energy performance of her latest single, We Found Love, and a remix of Cockiness.
We Found Love won her Video of the Year, defeating fellow nominees Katy Perry for Wide Awake, Australia's Gotye with Somebody That I Used To Know, Drake featuring Rihanna with Take Care and M.I.A's Bad Girls.
But One Direction, who came together after entering as solo contestants on British talent show The X Factor, confirmed their pop firmament ascendancy only six months after arriving in the US.
Their video for What Makes You Beautiful won them both Best New Artist - beating Fun., Carly Rae Jepsen, Frank Ocean and The Wanted - and Best Pop Video, besting rivals including Canadian teen sensation Justin Bieber.
They also won the Most Share-Worthy Video category, to take home the most awards of the night.
Elsewhere in the main categories, Nicki Minaj won Best Female Video for Starships, beating Perry's Part of Me, Rihanna's We Found Love, Beyonce's Love on Top and Selena Gomez with Love You Like a Love Song.
Best Male Video went to Chris Brown for Turn Up the Music, against shortlisted rivals Bieber for his Boyfriend video, Ocean's Swim Good effort, Drake featuring Rihanna with Take Care and Usher's Climax.
Other notable performances at the Staples Center show included Grammy-winning country-pop star Taylor Swift with her sing-along We Are Never Getting Back Together, while Alicia Keys played the thumping Girl on Fire.
