Katy Perry's producer, Dr Luke recently worked with young artist Marina And the Diamonds for her brand new single Primadonna which will feature on their upcoming album Electra Heart, due to release April 30th.The track is actually an upbeat one, fun disco pop anthem completing perfectly with Marina's distinguished vocals which she first unveiled during some live sessions last week: You say that I'm kinda difficult\u002F But it's always someone else's fault\u002F Got you wrapped around my finger, babe\u002F You can count on feeling misbehaved\u002F Primadonna girl,\u002F Would you do anything for me?\u002F Buy a big diamond ring for me?
