Katy Perry wore a zebra print micro mini skirt that perfectly coordinated with Rebecca Black's leopard print mini dress for a duet of 'Last Friday Night' in LA.

Rebecca, meanwhile, donned an equally short leopard print mini dress with a flared skirt. She wore black heeled knee-high boots, switching these for cream fluffy over-the-knee boots and a matching her white faux fur coat after she'd finished her performance.
