Cyrus in foul-mouthed tirade against 'scene stealer' Gaga

Miley Cyrus branded Lady Gaga a "scene stealer" for her entrance at the American Music Awards (AMAs).

'Applause' singer Gaga entered the ceremony, held in Los Angeles, on a human-powered white horse, causing Miley - forgoing her usual risque attire to appear in a demure white suit - to vow to beat her at the next event.
