Grammy Awards: Music stars on Los Angeles red carpet

Pop star Taylor Swift kicked off the 55th Grammy Awards in Los Angeles, the most prestigious music awards in the US.

Officials had warned artists ahead of the awards "not to show too much skin" after several performers wore revealing outfits at last year's event.

The BBC's Alastair Leithead reports on music and fashion, as stars including Adele, Justin Timberlake, Jennifer Lopez and Sting arrived on the red carpet.
