Justin Bieber swept the board at the American Music Awards, capturing the four prizes he was nominated for.
But in an impressive display of girl power, it was the ladies that dominated the proceedings at the weekend's high-octane ceremony.
Later the singer – who has revealed she's expecting a girl – proved she's lost none of her energy.
She belted out her single Raise Your Glass in culottes, a gold jacket and a skimpy bra top.
Meanwhile, the new Mrs Russell Brand, aka Katy Perry, performed her hit Firework wearing a sparkling red all in one catsuit.
