That would be Lady Gaga, of course, who pre-Miley was accostumed to owning these events. Tonight, the singer arrived on scene poised on a Trojan horse (powered by two hidden humans inside), dressed in a Grecian gown...and right smack in the middle of Cyrus's red-carpet interview.
Indeed, Cyrus was dressed in an uncharacteristically low-key outfit — a simple while pantsuit accented with tasteful hair and makeup — and was giving benign commentary on the special performance she had planned for the awards show in honor of her 21st birthday, which she celebrated Saturday.
Speaking like a jaded veteran of red carpet wars, Cyrus was impressively humorous about her rival's splash. "What a [expletive] scene stealer," Cyrus noted dryly. "Next time I'm coming in on a dragon."
